I masterbate about 1-5 times a week, for starters, and when i am masterbating, i orgasm fine, and ejaculate fine, but more often than not my left testicle retracts up into my body at the point of orgasm. It has a slight pain/ feels funny/ uncomfortable, and it feels like this after im done for anywhere to a few minutes to a few hours. My left testicle is also a little smaller than my right. Im also 17.
I'm worried that if i dont get help soon, or find out that its ok, that i may screw something up for later on down the road
Thank you for any help.
