He didn't pull out...

First I want to say please dont judge me. I am coming here for support, so please dont tear me down. :)

Anywho ok so my boyfriend and I have been together for a while and we have talked about having kids in the future and never really put a timeline on it. So we are kind of in the not trying not preventing mind set. We use the pull out method lol I know its not a fool proof plan. But the last 2 times he didnt pull out. Like at all. I didn't say anything and neither did he. Should I talk to him about legit ttc? We are financially stable enough for children and its definitely something we want

UPDATE: We are officially ttc!
