From my overnight until today research, there are ACR and DSS mods that can do the trick.
However, the 2 mods have so many features that I don't need, and the added features going to confuse me because I already have many mods in the game.

Cyjon's No Date Age Limit mod seem to be the answer for this problem. But I couldn't get it works, also I can't find any feedback from other users who have used this mod too.

So far, the closest thing I can find is twojeffs's teen/adult relationship mod, and jenflower woohoo teens. Both of them are small features mod like I want, but it's just one step away from my target age.
Here's the link for the 2 mods.

Can anyone help me on this search please? I just want to create a less capable male sim(like elder sim) to have romantic relationship with teen sim.

Have you tried the Woohoo Teens mod? I don't think the game treats adults as different from elders with regards to dating as adults can date elders. So if it allows adults to date teens then it probably allows elders to as well.

You need woohoo teens for that mod to work.

You will need one of the teen woohoo mods to have teen date elders regardless of Cyjon's mod which requires Woohoo Teens.

I've installed both Jenflower's teen woohoo mods and Cyjon's mod already, but my teen sims still don't have romantic interaction for elder sims like flirting, romantic hugging or kissing.
However, I just notice that both target sims can do romantic things in a hot tub, sofa(only peck kiss), and on a bed. The only times they can't do such things are when they're standing on a floor.

Maybe other mods might cause a conflict with the 2 mods, I think I'll try to remove some of them tonight and see if there are any consequences.

@zombiefish: I'd like to know how you get on. Like Charity, I thought Jenflower's Woohoo Teens would work just as well for elders as for adults, but I was surprised that, when I did a quick test in Veronaville, that, after installing Woohoo Teens, my elderly Smythe sisters had no romantic interactions available with teen Julian Moltke, although they very good friends with him. At least none were available when they were standing up. I would expect that Julian, who is in a steady gay relationship would reject any such advances, but I would have thought at least the "Flirt - Check Sim out" action would have been available. So it looks as if you're right, and Woohoo Teens doesn't properly enable romantic interactions between elders and teens. Now I really don't want any romantic relationships between the Smythe sisters and Julian (because it would wreck my story!), and I was only looking to see if the options were available in their pie menus. So next I'll try to do a full test in my test 'hood and see if I can get an elder to seduce a teenage boy or girl (or vice versa). I'll report back here what happens.

If you have Apartment Life EP there is the strip down version of InTeen called Wild Child. http://www.simbology.com/smf/index.php?topic=8601.0

Do you need to make the teen pregnant by a elder, if so you have Chris Hatch mods "Alternate Pregnancy Controllers" and his Free-for-All bed. Both at "BackAlleySims" BAS for short.
BAS is an adult site. (These 2 mods will allow elders to get pregnant and have a baby.)


twojeffs mod only allows attraction between teen and elders and needs ACR to have relationship. "Adult/Teen - Teen/Adult Attraction - Recommended additional mod for ACR"

I have actually been looking for an easy to work teen/adult relationship hack. Inteen scared me off and there were a few bad reviews of Woohoo Teens and Wild Child (plus, complicated again). So, I put on my puppy dog eyes and asked Chris Hatch if he could add teen/adult Maxis romantic interactions functionality to this.

Warning: It is an adult hack and an adult site.

http://backalleysims.com/adultsite/...raction-updates

And he said yes! Just add the file here http://backalleysims.com/adultsite/...updates/page133 and voila! I tested it and it let my teen and my adult do all the flirt, kiss, hug etc. stuff and even go on a date (I don't have Cyjon's date hack). The one thing it won't do is set crush or love flags (okay, now there is a version that does crush/love, but only for AL/M&G).

So, I then thought, what if and the friend who had come home from school with my teen got an instant age up to elder and elder/teen romantic interactions worked fine as well. Admittedly I only tried a flirt and a kiss; you'd have to test the others yourself.

You need the bouquet on the lot for it to work, but you can change it into a book and bury it under the house if you don't want to see it. It also allows you to set autonomy etc.

The JSW bouquet is almost like ACR and has a lot of action on it just like ACR. Where did you read bad reviews for Wild Child. The only thing so far that I can find to conflict with WC is other teen woohoo mods.

The autonomous action on ACR can be turn off where only player controlled action can happen.

JSW bouquet must be in the room for teen/adult/elder action to be able to be done.

Ancient Highway had a good old whinge about Wild Child in the thread where it was posted. But it was Woohoo Teens that some people complained about problems with.

And the bouquet doesn't have to be in the same room, just on the lot.

The thing I don't like about ACR is that you can't exempt sims easily. Everyone gets a token and you have to work to set it up. With the bouquet, if you don't put it on the lot then you don't have to worry.

I tested this quite extensively in my test 'hood. I created a rather seedy looking elder Romance Sim, and a couple of romance teens for him to try to seduce. With woohoo teens installed, it was just as OP described in post #4. None of the "standing" romantic actions were available between elders and teens. But the actions on the sofa, in the hot tub or on a bed were available. (I wonder if the thought of romance between elders and teens was too much for Jenflower, and she took them out. But she missed the ones in bed and on the sofa?) By sitting the teen and the elder together on the sofa, and them relaxing together on the bed, I was able to get the relationship to the point where they had a crush on each other. I don't think the at-table flirt/kiss interactions were available either. But the Throw Food interaction was available, and, incredibly enough, that does count as romantic, so when the elder threw food at the teen, the teen fell in love with him. At that point I glanced at his aspiration meter, and it said he was a "Dirty Old Man"! How appropriate! So in summary, you can have a romantic relationship between a teen and an elder with just Woohoo Teens, but with a rather oddly limited set of interactions available. They can make out on a sofa and woohoo in bed, but can't manage the mildest of flirts standing up. But they do develop Crush and Love tags.

So then I thought about the file that Chris Hatch had made specially for Charity (the second one she links to in post #7). It provides all the romantic interactions, but not the Love and Crush tags. How would it be if I used both it (to provide the interactions) and Woohoo teens (to provide the Love and Crush tags)? It took me a while to understand how to get the Back Alley Sims stuff to work (to get the [very adult and explicit] interactions to work, you need the bouquet, and the interactions and the animations), but, when I did, I found that, with Woohoo Teens and the Bouquet (as modified by that special file JSW-ExtendedTeens.package that Chris made for Charity), I got exactly what I wanted. The elder and teens had, when they had reached a high enough relationship level, all Maxis romantic relationships available, with the Love and Crush tags provided by Woohoo teens. Now I must warn that the BAS interactions are very explicit, and you may not want them in your game. I think it may be possible to use the bouquet without any of the BAS interactions to get just the Maxis interactions, but I never actually tested that. You would need the bouquet (JSW_adjusterbouquet.package), the special file JSW-ExtendedTeens.package as well as Woohoo Teens. To make this work I renamed the special file to xJSW-ExtendedTeens.package so it loaded after Woohoo Teens.

There is, at the moment, a catch in all this. About a day after he put that file available for download for Charity, Chris Hatch took it down and replaced it by one on page 1, which I believe supports Crush and Love tags. But (1) this replacement requires Apartment Life, and (2) it doesn't support relationships between teens and elders, only between teens and adults. I wonder if romance between teens and elders is too much, even for Chris Hatch? Surely not! I was just lucky enough to download the file during the day or so that it was up. But Chris does seem to be one of the most obliging of modders, so perhaps, if we ask him really nicely, he'll put it back.

Sorry this has taken me so long. I tested it for quite a while, and then got side-tracked onto other things (like adding OFB to my game). Ihope OP is still interested.

During this testing I got to quite like Woohoo Teens, and think I'll keep it in my regular game. Even though my teens seldom Woohoo (which they could do in the Easy Bed anyway), they do quite often sleep together. Woohoo Tens lets them share any double bed, not just the Easy Bed, and lets them snuggle up together in it when they're asleep. I think it's worth having just for that. Like OP, I prefer that to the complexity of InTeen or ACR. I believe there are some problems with Woohoo Teens, but I haven't seen any myself so far. Does anyone know what these problems are?

As for the Bouquet, I think I'll use it in a couple of 'hoods, but not in Veronaville. I just might occasionally have children wanting to see my game!

The bouquet version I have does support teen/elder relationships. I just tested it.

Pictures attached of a teen/elder kiss and a teen and an elder sleeping together. Yes, they are different elders, but the townie I was testing on had the temerity to say it was too late and bugger off right in the middle of testing, so I had to catch the next one who walked by. XD

You do need to work the relationship up a little though before romantic options will appear. Also, the lips don't meet because of the height difference.
