I'm a male. If I go in for a standard STD test, what procedures should I expect to have done to me?

Once again, another answer provided from the male perspective by Andrew.

Typically, you can expect a blood test and/or a probe into the urethra via cotton swab. It doesn’t hurt too much. In fact, some men actually like it. They have a word for it just to describe the practice of entering the male urethra for pleasure. It’s called “sounding.” For those of you men who enjoy urethral insertion, rest assured that you aren’t alone in this fetish.
