You should be ashamed!

What I really need is your advice. I am a 16 yr old girl who is utterly ashamed of herself for having sex with 4 different men, all of whom I did not have romantic interests in, it was only for the sex. I am in total regret and I am constantly wishing I had never had sex with these people. Part of my guilt comes from the fact that I am a very strict Catholic, I myself still believe in finding someone I love, marrying them and until then, giving myself to them completely. I obviously have contradicted my belief and hence feel completely horrible about it.

I guess you can say I am self-slut-shaming. Dear Ladies, what do I do?
