Took my boyfriend’s virginity

My boyfriend and I are both 24, this is his first relationship ever and I’ve been in several and wasn’t a virgin going into the relationship (I have a son). He was wanting to wait until marriage because he’s catholic, but on Valentine’s Day, one thing led to another and we ended up having sex. Multiple times. Over the period of three and a half hours. It was awesome for both of us and he enjoyed it and all was well, but the day after, he was struggling with a little bit of guilt, because he was trying to wait for reasons that pertained to his religion. Does anyone have any thoughts? Advice? I’ve never been in this situation before.
