Okay so my boyfriend and I started having sex in late September. He's my first serious boyfriend and I'm his first serious girlfriend (I'm 18 he's 21) and is having sex for the first time was a spur of the moment thing, we didn't plan it at all. He's in the marines so he's been gone since mid-October with only two short breaks home (about two weeks all together) so we're still pretty new to sex. Well when we had sex for the first time I wasn't on birth control, I've been raised by a single father and I'm sure it would look off if his 17 year old (at the time) daughter got her first serious boyfriend and a few months later asked to get on birth control and like I said we didn't plan it. So we have used pull out. Since he's been gone most of our relationship we haven't worried about birth control but he's coming home in August for good and wants us to maybe look at apartments. I don't believe in birth control though, I've always been against it just because I don't like taking medication and putting things into my body that don't belong. Any advice?
