I cry after sex. Every. Single. Time.

I'm 19, almost 20. I love my current boyfriend. We've been together for almost two years, and he's honestly perfect for me. But I'm incredibly unhappy with our sex life, and it's not his fault at all. He's very attentive and makes me feel so loved and sexy, but every time we have sex or do anything sexual I cry after. About a year before I met him, I was in a toxic relationship where I was coereced into having sex and raped on one occasion. I've gone to therapy for this, but I feel like this is somehow still affecting my sex life and I honestly am just at a loss as to how I can deal with my baggage. I'm tired of feeling guilty about having sex, and I'm tired of being scared to talk about this. It's beginning to strain our relationship, and even though he's trying to be understanding he's also expressed to me (respectfully) that it's starting to frustrate him. I totally understand where he's coming from, but I just don't know what to do. Does anyone have any tips?
