Sex and being a Christian?

By no means am I perfect. I believe in God, pray everyday, and trying to go deeper into it like I used to be when I was younger. I lost virginity at 16. Long story short my mom found out and now she shames me about it..because of my age, being a Christian etc. I hear it all the time that I’ll feel “dirty” “regret it” guys don’t respect girls who “give in” it’s really starting to give me a complex associated with sex and with being a woman;having urges. With hearing that all the time it’s starting to make me think I’m used goods, or low value of a woman. Is it a sin or am I a bad person because I engaged in sex before marriage? Does God think I am low value? Starting to think my mom does.
