Paranoid. 😖

so my boyfriend and I have been going out for over a year now. We have sex regularly ( 3-5 times a week) and I've been on birth control the whole time. When we first started having sex he would Always pull out, just in case. But lately we decided that it was okay for him to cum inside me, since we've never had a problem before and I've been on BC so long. Not every time, but a couple times a week. Is this okay??? I haven't had any problems so far and I'm not pregnant either. But should I risk it??? Help! 😩
