Worried

I have been experiencing these weird skin sensations in my mid section all the way down to my lower thighs.  I was tested about eight to ten months ago for std's.  All tests were negative, they were blood testing antibodies etc....Since the last four months or so I been experiencing weird skin sensations, it feels like someone stabbing my thighs, they get warm and then it goes away.  My scrotum sometimes feels like it moving or tingling along with inner thighs. This always seems to be when I'm sitting, especially when crossing my legs. I've been to my dermatolagist several times scared thinking it was herpes II.  He keeps telling me it isn't.  My penis skin below the head has been irritated in one spot for awhile and it's very annoying, mostly when something rubs against it I freak thinking its coming back.. I've never seen any  blisters or groups of blisters.  I'm always pulling on my penis now looking for things and notice little things that freak me out.  My testicles used to get really red and then leather looking, my dermatologist said that it was called lichen something cause from stress, and I've been really stressed since the beginning of the year.  I'm seeing an uroligist tomorrow for a urine analysis to see if theres any other forms of internal infection.  I've had back problems since high school, one time where I couldn't walk for a week.  My research has suggested these symptons could be stress related, too much mastubation causing dry skin, herpes, or possibly a pinch nerve somewhere.  Any ideas?  FYI, I haven't had sex since October of 2006, my girlfriend at the time had a yeast infection.  She was the last person I had sex with and we started dating in august of 2005.  She's never had any signs of herpes but did have a bump once. Test results showed that it was HPV.

Don't worry about HIV or STD, you almost certainly don't have it.
I will bet that no doctor will tell you anything specific either.
Just ignore this stuff.

There's no such thing as "too much masturbation", unless you're avoiding other people and school, work, etc. to stay home and masturbate, or you're spending money you don't have, going deeply into debt on masturbation accessories. Masturbation is good for you. It's healthy. It teaches you about your body, about your sexuality, helps you become a better partner, helps you relax. Frequent ejaculation may also help prevent prostate cancer. It most definitely does NOT cause any symptoms you describe.

And those symptoms don't sound like any STD, either. Listen to your doctors. If you have lichen sclerosis, or lichen planus, those aren't STDs. Google them for more info. Much of this does sound anxiety related, and you definitely sound anxious. Have you talked to your doctor about medication for your anxiety? How about therapy?

Bud, pound that pud...  just dont cause any friction abrassions or shoot yourself in the eye.

Just kidding.

Seriously, this does not sound like an std, and you arlready are seeking medical assistance.  Good on you

you guys are too funny, often when hungover I can go to town like three times a day... For the last four months or so I noticed dry skin at the top afterwards, not dry semen. lol....  my X girlfriend had hpv, non cancerous strains, which means i mean i'm a carrier and Ive had one breakout and had them removed.  I wondering if these symptons are from that.  I have had anxiety issues since 2002, it comes and goes and my life has been extremely stressful since the beginning of the year.
