I hope that this doesn't continue to become a problem for you as far as the wanting children
part. I have 2 questions for you. 1) has he been to the doctor concerning his in ability to ejaculate? 2) you may have to go through a fertility specialist, if it is only for insemination. In this you wouldn't need fertility treatments nor would he, they would just take his sperm (after he has deposited it in a cup) and inseminate you. That requires no surgery in case you are wondering. It isn't like InVitro at all. They just put it right where it needs to be at that perfect day. PM me for more info on this if you would like. That wouldn't be a costly way of getting pregnant either, since there wouldn't be drugs or surgery involved on wither part.
One thing to remember though, when trying to conceive...watch the "artificial" lubricants. They can
kill sperm deader than dead.
