I'm 14, and I have very large veins aboove my left testicle but do not hurt. My left testicle also has relativley big veins behind it when they're not tight. I sometimes get achy feels (but not very often). My left testicle drops down alot further than my right one and like i said, it's very veiny, and i can't feel alot of my left testicle sometimes because of all the veins, but then sometimes i can, but the veins are still there. My left testicle is becoming alot smaller than my right one, and i can barely feel it because of all the veins etc like i mentioned above.
Sorry for bad explanation!
I'm really frightened to do anything with my gf because of this incase she sees, also afraid of what may be infertitlity - i don't know
Thanks
