My boyfriend is a paraplegic and the doctor said that he could not ejactulate.
It is kind of hard to put into words... but his head will still swell up like he was just about to but I don't ever see anything, is it possible that I could still get pregnant... and yes we are trying

There seems to always be an anecdotal story about someone who got pregnant in the same situation, no matter what that situation is.

If you are determined to get pregnant, you should see a doctor together and discuss the options. (Doula, what kind of specialist would they see? Urologist? Reproductive specialist?)
