What am i doing?

Hello.

I am 23. My bf is 33. Ten year difference. We love each other. We make love maybe seven times Max a month. This is due to long distance relationship. I'm planning to move where he is residing in within a year. We have been sexually active for more than a year now. I am not on birth control and we do not use protection. And yes he finishes in me. Sorry for my bluntness. Never have I got pregnant. And my periods are never consistent. Am I able to have kids? Not that I'm trying too. I mean that's crazy considering the circumstances. Maybe I'm overreacting. What do you think?
