I think it's actually quite simple once you boil it down to supply and demand: 1.sex sells, always has, always will, regardless of type (straight, gay and anything else) so modders will mostly go for the ones that will make them the most downloaded, endorsed or donated (although of course there are plenty of mods out there that are simply labours of love, with no financial supported wanted) 2.quite a few of the people wanting said mods are young, probably straight guys, with zero to little experience with women and breasts on their mind 24/7, as someone pointed out earlier in the thread ( and I say this because 12 years ago when I first joined nexusmods, that was on my mind xD) But for me personally, I usually just add some for eye candy or roleplay purposes, I don't even add sex mods at all anymore xD; and my latest playthrough I went vanilla. I guess growing up, getting a job and a serious relationship simply made it redundant for me, that and all the hassle of making the mods work well without breaking. Feeling the age after remembering I joined 12 years ago :ermm:
