I feel you bro.
Just started seeing this girl, and yesterday was only the second time we've had sex. First time was bad because of her vaginismus, yesterday was a bit better. She's on the pill and she reported not being as horny. She would also masturbate more prior to taking the pill. She also revealed taking medication for some mental issue, "feeling sad". I asked if it was antidepressants, but she said no.
I don't think I'm sticking around for this. I don't want to hurt her further. Just like you, I immediately told her to get off the jew pill.
