Sex for me

My boyfriend and I have sex like once every month... Maybe. We don't live together have been dating for 2 years and my parents always told me no sex before marriage. I'm 22 years old and my boyfriend and I had sex after dating for 3 months! I felt so guilty. So we didn't have sex for a long time. And then we did again. A few months later. It really bothers him that I don't like having sex. And it bothers me too. I want to, want to have sex with him all the time. I am not sure if it's cause I feel guilty or if it's cause I have a low sex drive. Does anyone else have this problem?

Also this one time we had sex I finished and then started crying really heavily. Not from guilt or pain.... But I think from just being overwhelmed with emotion. Is that weird? Someone help! Lol
