Hello,

I guess I'll be frank about this: I'm an 18 year old experiencing major emotional problems regarding his sexual being. My problem is that my testicles are small; to be exact, they're probably about the same size they were when I was 8. They're not showing signs of growth at all, which worries me and makes me feel incredibly inadequate (I can't even function normally in gym class). To make matters worse, when they shrink due to change in temperature it's minutely painful. I'm not sure if this has any part to it, but there's a huge scrotal vein running down the middle of my sack, and it's been there as long as I can remember. Everytime I look down there and feel around, it feels like they're shrinking.

I've been to the doctor already regarding this, and he assures me everything's fine, even after having endured being struck thrice with a metal tennis racket. My testesterone levels are normal according to test results, but my sperm is always "agglutinated", or whatever the term is. Given that everything regarding my testicles seems out of place, I find it hard to believe that everything's alright down there. If anyone could shed some light, it would be greatly appreciated; It's causing me mad relationship problems.
