Scared sex

Why do I alway get so scared when I have sex. I do it because it makes me feel so close to my boyfriend and I want to, but afterwards I always get so nervous. I always make him blow up the condom to make sure there are no breaks and so far none have broke. We only do a few pumps and then we stop cause I don't let him cum inside of me. No chances of pregnancy right, just need to ease my mind
