Doctor, I have one more thing to ask you...
It has been 24 days since my sexual encounter ( received 1 minute protected oral sex, no visible sores) . I feel like I am probably stressed over nothing but my anus has been itchy. When I wiped today there was even a little blood. The toilet paper at University is real rough so it could just be chafing. I feel like it wouldn't still be itchy 24 days after the fact but I don't really know. Thanks again for your help before and I promise this is my last question...
From your description, this really can't be herpes. Although recurrent genital-area herpes outbreaks sometimes are on the buttocks, upper thighs, etc, the initial infection always directly involves the genitals, anus or rectum. Also, herpes does not cause the sort of bump you describe. One way to look it is that herpes lesions are "on" the skin, that is, quite superficial; lesions "in" the skin--that is deeper lesions, like pimples--almost never are herpes. Yours sounds much more like that. I'm sure the timing of its onset with the sexual exposure you describe is purely coincidental.
Lack of having cold sores is meaningless. At least half the population over age 20 has been infected with HSV-1, and that proportion is the same in people with and without histories of cold sores or other symptoms of oral herpes. So regardless of that history, there is at least a 50% likelihood you are immune to catching genital herpes due to HSV-1.
Anyway, relax and put herpes out of your mind for this event.
Good luck-- HHH, MD
