born again virgin?

my boyfriend and i have been together for over 3 years. we started dating in high school. so it was like, one year in high school dating. one year long distance dating. and now we live together. i have NO sex drive at all. like it’s been a couple months lol. i feel bad because his drive is so high but he’s super understanding about it. i’ve been on medicine for it, didn’t help. i’ve tried so many things i’ve read on the internet. i just want to get back into it and have a healthy sex life again. i think the only time we actually had a good sex life together was when first started dating. i’m young, 20. i shouldn’t have this problem. my mom has sex more than me. my grandmother has sex more than me. please help
