Next Step??

I've been with my boyfriend for almost 7 months, and we just started letting him finish inside of me. (I am on birth control which I take religiously) We both know that we are each other's person. We just clicked since the start of our relationship which is amazing, we've been through a lot an example being we lost our virginities together and other things along those lines. I thought I'd be nervous about him finishing in me, but honestly I am not. I know he's my person and whatever happens, happens. 🤷🏼‍♀️ just wondering is it normal to feel a little crampy afterwards? Thanks!
