How do you folks go about getting confidential STD testing?  There are many web sites that offer it.  Any particular ones that you recommend? Or do you go through your doctor?

Or go to sites like gettested.com  it's confidential.  

GOTTA REMEMBER THAT ONE. THANKS!

Every 90 days is not really that suspect, I am not married, and it's not his business to worry about they 'why.' Most docs are happy to take your money, and appreciate the fact that you get tested at all. I tried the community clinic, but I feared a MRSA infection upon arriving. I would rather just pay more.  

...was when I told him that the provider (who gave it to me) said she got it from using her roommate's Hitachi. LMAO with my GP. After he stopped laughing, he said: "that's a slim possibility."

In the remote chance you get HIV positive,  they are required to divulge your identity to health department.   I'm sure there are other diseases included in that list.  No idea if this law applies in every state though but the law exists where I live.  

I go to one of the commercial outfits here in Atlanta i.e. anylabtest. Walk in, tell 'em I want to pay cash. They give you a form to fill out where you write down a fictitious name and address. Pay, get a receipt, and leave. Come back a week later, show receipt, get results. Book appointment!
