First I would like to thank you for your time reading this...
I'm 23 years old and I don't masterbate that much, maybe 3 or 4 times a months, but a few weeks ago i've started to feel some pain while masterbating above my penis in the lowest part of my stomach, and I never feel this pain unless i'm masterbating. I've looked into the male anatomy and I guess the pain is coming from the "vas" which is a tube through which sperm is carried for exiting, i'm not sure though...Any suggestions what is that pain caused from? Help me please...
