Getting on birth control

So I need help I want to get on birth control because of the guy I am seeing right now he likes to blow inside me usually I don't let any guy do that there just somethings complete different about this guy. Outside of the sex life with him his sweet and amazing charming makes sure I am happy notices if there is something bugging even if it's a little thing he blew off hanging out with other people to be with me. I've known him for about a month now we just had sex Tuesday I've been over his house before just chilled and watched movies and cuddle that was all. Tuesday was different 100% different he made sure none of his friends came over made his room mate leave i was pretty tied just had got off work at 2 in the morning I just wanted to sleep and he let me. I had woke up around 5-6 because he was GONE! he want to cook us some food sweet right and boom started getting in the sex.
