My worst nightmare if anyone were to ask would be that I can’t conceive..

My boyfriend and I of 3 years don’t use protection we always use the pull out method. We’ve talked about marriage and kids. We’re at the point in our relationship where if we get pregnant we’d be so happy so grateful to have a child of our own. I’m just starting to think A: he’s really good at pulling out or B: I can’t conceive. And that really scares me.

Its not like we’ve been trying to get pregnant it’s just a weird thought that has been crossing my mind once in a while. Has this crossed anyone else’s mind or am I alone in this twisted mind fuck?
