Brief Answer:
It could be medication if you receive one

Detailed Answer:
Hello,
Thanks for using Healthcaremagic.

I read your query and understand your concerns.

There are number of medications which can cause retrograde ejaculation. Flomax and other medications of its class causes retrograde ejaculation as side effect which means semen goes in the opposite direction and do not go through penis during ejaculation.

This is one of the common side effects and most patients recover well on discontinuation of flomax.

So this could be the one reason for not having semen discharge during orgasm.

If you do not receive any medication please revert back to me with available reports.

I hope this helps you.
Thanks and regards
