Addicted or Something More?

"I'm not sure how to explain this but I think I may have an issue with masturbating. My Gramp is who suggested it after he found me doing it out in the garage one night right after dinner. I spend summer and holiday break with my grandparents who raised me and he said they hear me going at it every night and every morning. He says they don't want to embarrass me and that jerking off is normal but I'm well beyond the age of perpetual hard-ons. I'll be 33 next year. Anyway Thanksgiving is next week and I'll be with them for the entire week and I'm kind of worried about it.
I do masturbate every morning and every night just like he says. But I do it lots in between too. Every break time at work I hit the men's room sometimes even do it standing at the urinal. It's like I'm so hard and it hurts so much I can't wait long enough to even go into a stall. After work I sometimes don't even get out of my car and I'm stroking my boner before the door even closes. Then I can never go past 730 or 800 without doing it again.
I've never had a longterm relationship. One lasted a few weeks until in the middle of watching a movie she found me in my room stroking my dick. To be fair I tried to get her to have sex and she wouldn't. I didn't push it but I really needed to cum. It's not just that my dick gets hard it gets super hard and my balls feel real heavy like they'll explode if I don't cum like a constant case of blue balls. Am I addicted to jerking off or is there something more going on here?"

Whew.... Well, that's a lot of jacking off, isn't it? Being addicted means everything else takes a back seat to the masturbation; you don't sleep much, don't eat much (unless you can stroke while you're eating), you avoid activities with friends and family so you can stay home and wank, and call out of work sick just so you can stay home and stroke your cock. That's addiction.

Since you don't describe it in those terms, and because you complain of heaviness/ache in your testicles a mere couple of hours after you've had an ejaculation, I'm going to guess there's something more going on here.

There's an old term: Over-sexed. That meant getting laid and still not feeling satisfied; it's an over-saturation of hormones. Those with low Testosterone (T) have a low libido (low sex drive); those with high T have a high libido. It sounds to me as if you have extremely high T levels. By your age, T levels should have started dropping. You might want to have your levels checked. But other things could be at play, here.

According Holly Lucille, ND, RN, a naturopathic doctor, in an article in Everyday Health, "When it comes to inappropriate higher levels of testosterone, there are underlying conditions that need to be ruled out. The first that come to mind are hyperthyroidism, adrenal or testicular tumor, or precocious puberty."

Since you are way past puberty, seek out a Urologist who specializes in sexual functioning. Tell him/her how many times per day you ejaculate and why. Explain what you've told me (the heavy/achy testicles, the feeling you need to ejaculate or they'll burst). You didn't mention it in your letter, but take note of the volume - does it decrease each time you cum during the day, or remain the same? Be specific - such as: if you experience pain or tenderness in the lower abdomen, near or next to the base of the shaft (the general area the spermatic cords travel out of the scrotum and into the abdomen).

Masturbation - even frequent masturbation - is normal. You should be able to enjoy it without fearing there's a problem.

Readers, any other suggestions?
