So I went on a date with this girl and when hanging out she decided

U grab her by her pussy and say "this! This is wat i like! This is wat i want!"

you are right in thinking that, op. one of two things happened; either she thought that you were actually gay and was trying to hook you up or she was quite simply straight up insulting you.

drop her.

You blew it. You're the only straight guy for a mile with the woman, surrounded by non-competition. An alpha would've owned that, had his hands on her the whole time and made a great impression on the girl.
Instead you got all butthurt and angsty now she probably thinks you're a closet fag, or at least an insecure beta not worth dealing with.
