Hi we have been trying to have a baby conceived. But I am a little hesitant to go to a doctor for a sperm test, as I am a Traumatic Masterbatory Syndrome male. I dont feel any problem during sex and I do ejaculate inside my wifes' vagina.
but now that I go to a doctor for sperm collection, how will I give sample ? I am sure I will not be able to ejaculate inside a test tube

I have tried abstaining for around a month and then do the hand way, but never got to ejaculate.
any advise would be welcome.
I am 35 yr male, I dont know at this age i will have to unlearn TMS and do it right way, am also not sure if that's possible
