emotional sex

my boyfriend loves penetration as do most men, and I'm not really into it , it always hurts, but a lot of times I do it because I k ow he likes it, but I ways get really emotional afterwards and cry. IDK WHY ?? has this ever happened to any of you ladies?? it's not because it hurts, maybe it's because I just feel really used afterwards, but at the same time I voluntarily do it ...any advice would be much appreciated EDIT.. we have talked about it a lot , and sometimes I do enjoy it but for the most part it hurts and I don't like it
