It's weird, really. Irl, vaginae are the grossest thing, but in 2D, they somehow are less appalling than dicks, at least to me.
Anyway, regarding your question, it's probably just context. Rivalry can be understood as just another form of affection, and some of the girls have relationships with each other that can be easily evolved into a romantic plot.

And please do not make derisive statements regarding other peoples' fetishes, the only people that need to be systematically euthanised are NTRfags.
