Help find sex mods please

[nojedzto]

I'm having a hard time figuring out the mods here so I need some help.

I'm looking for a mod that will allow me to initiate sex or introduce it into the game in some other way and have dedicated animations (preferably M/M but not necessarily).
It would be nice if this worked with atomic muscle but I can consider other bodies.

I can see a lot of four-play mods. I don't know what it's compatible with (animations, models). Is there anything better and simple?
