Why nature made this discrimination, 90% women are somewhat bisexual but 90% men are 100% straight?

I have straight female friends and other women I have interacted with + my real life experience say.The claim themselves straight, but watch lesbian porn, make out with women, check out women, experiment with women. Many girls claim they are straight still they have sex with another woman, performing cunnilingus on them, they performing cunnilingus on her, fingering each other, and scissoring, they did have an orgasm during the cunnilingus. They are not repulsed by same sex sexual intimacy. Photos of hot naked girls turn them on. They get wet so easily when they see a hot girl naked not necessary doing something sexual.

She is my friend I have seen in her profile 100% got crazy when she upload a sexy photos. I have heard from her that most women have sex, makeout with their female friend when they live in hostel. It's 90% women, that's why I asked.
