I guess you should know there's two sex frameworks
The original SexLabs came out in 2013, and is where most of the degenerate LoversLabs mods originated, including creature sex. Osex/Ostandalone(OStim is the new standalone version which is easier to install) came out later and most mods have integration for both, although Osex runs smoother, animations feel/look more realistic and it's easier to control what happens, but SexLab still has a lot of mods that you just don't can't get with O, like creatures (not my thing, O community just doesn't allow furries in to the chagrin of those degenerates, don't really care but it would be nice to have sex with the new Female Giant model by PSBoss).
Examples are fertility mods;
Baka Fill Her Up/SexLab Inflation Framework
Flower Girls (? Pretty sure its O compatible just forget what it's for)
Basic Pregnancy Cycle/Hentai Pregnancy
Fertility Mode/Being Female (from what I understand Being Female works better so I'll try it now, but I've only ever used FM+ and have had pregnancies but no confirmed births... in game)
NTR mods, if I'm not mistaken, there are only two/three, and they only work with SL
Shadowman's The Curse (you get a cuckold curse)
SLSF comments (which you need Sex Fame/basically a sexual reputation mod)
and... Further Lover's Comfort/Enhanced Spouses, I believe?
and then each framework has an Arousal mod/Cum mod, different animations, etc.

Don't forget you first need a skeleton mesh, a physics mod, and a sexy body! If you can't get at least those three working by now everything I said is basically alien to you
