sex after my pregnancy! 🙊😬

I got pregnant at 16. My son turned one a few weeks ago. And honestly I haven't had sex since I found out I was pregnant. I now have a boyfriend and he's not pressuring me or anything, I just want to be able to please him. He's given up a lot actually to be with me, and I can't even give him a simple thing in return. I'm just so scared that I might get pregnant again 😫. Don't get me wrong I love my son and he's my life! I just don't want anymore kids at this point in my life. Ugh I just feel so horrible for not being able to do that for him!!! And I know I'm just really in my head about it, I'm just freaking out!!!!
