Ngl I do wish same sex breeding was a thing. Sometimes my best breeding pair with the best skills to pass on just happen to be the same gender. Better than trying to catch one of the opposite gender or trying to breed for another while hoping they get good skills to pass on again.
Ah yes, the Gardevoir Syndrome. Anyway, someone in LL has managed to create framework that enables custom models for different sexes. The problem is now there aren't good enough models for that (current ones are basically edited models with dick/boobs slapped into it).
