I never want to have sex again in my life

I always get scared having sex. I recently had sex with my bf and he used a condom which I would have made him wear anyways but also because I knew that I hadn’t been taking my birth control like I should. I finished him off with a blow job and what not. In between that he slapped my ass and fingered me a little bit. I can’t exactly remember if he had anything on his fingers or not and it’s scaring me. It makes me feel like I should really stop having sex becauae this is always a scare that I have. Usually nothing happens and I’m fine and I just freak myself out. Should I just try to relax and not stress or should I be really worried. I feel like I’m not educated enough even tho I had sex Ed. I want to have sex but obviously I’m just not ready
