Boyfriend after sex

after my boyfriend and I have sex, he just automatically puts his clothes on and I just lay there. we've been together 11 months and this has been happening since we got together. and then after we do it, he's super quiet and doesn't talk very much like normal. I lost my virginity when I was 12 to sexual assault and he knows that, and every time we have sex he asks me if I am okay 373763 times. is this normal??
