Unhealthy view on sex?

Growing up I’ve always been told to wait until marriage. I decided not to wait. Now that my mom is aware that I’m not “pure” she says things before I go out with male friends, or just at random times... “all guys want is sex” “you’ll regret it” “you’ll feel dirty later on in life” “men don’t respect women who give it up” “to be Christian you need to abstain” I always fu*cking hear it and I’m sick of it. I’ve tried telling her that I don’t regret it, that it is normal etc. I’m 19 and am capable of judging who wants me for that reason only. I understand and know better to not give myself to just anyone. It’s giving me a complex and shame associated with sex and masturbation as a whole. It’s created a lot of problems mentally and sexually. Along with other problems and differences me and her have it’s really making me resent her. What can I do?
