Can’t get an E$&@¡k$¿ !!! 🍆⬆️🚫

So I’m currently 33 weeks pregnant. The baby daddy has left me and I’m currently dating a really nice guy for 2 months. So I decided that it would be a good idea to test the water in bed. Also see if he really wants to commit to me and my son. You know a test to see if we’d be a good pairing. Everything went almost great he listened to me, made me feel good, and I made him feel slightly good. The only one bad thing is he can’t get a full on erection and barely a semi-erection. Plus he’s 22 a tad over weight. I know it was nothing wrong with me because he did get a little bit excited and I was pulling out all the stops. I also know his penis size has nothing to do with his ability to maintain and erection, but his tool is only truly a good 4 inches. Which I don’t mind at all especially when he’s so caring and wants to take care of well the whole package I come with. I’m curious on what we should do though about the whole erection thing because I’m worried about me getting to attach then us wanting more child and him not be able to supply. I know it’s going to be a while before more children, but we still both have needs. Opinions? Other then leaving. Also what doctor would help in the bedroom area? I’ll be asking my obgyn about this too.
