This doesn't necessarily sound abnormal and certainly isn't herpes. As I said, you're not at risk for herpes or any other STD from the sexual event described.
Hello,
Thank you for the quick and informative response. I forgot to mention, I also have had minor irritation penis foreskin since this event and some white non- raised spots (looks like white freckles) no pain just a bit of itchiness. Should I be concerned about that? thank you again for your attentiveness.
Welcome to the forum.
In considering herpes risk, you should start with the understanding that even with a partner known to have genital HSV-2 (and not having a recognized outbreak at the time), the average transmission risk for full-on unprotected vaginal sex (several minutes duration) is probably around once for every 1,000 events.
When you consider that, you should understand that the chance of infection becomes extremely low for less intensive exposures. First, you don't know your partner has HSV-2. If we assume a 20% chance (about average for most women in North America), then even unprotected vaginal sex might have had a risk of 1 in 5,000.
And now we add that you didn't even have sex, only potential indirect exposure to your partner's vaginal secretions. Such exposures may in theory transmit HIV. However, if it happens, it's very rare. In my 40+ years in this business, I've never had a patient with genital herpes that seemed to have been acquired from such an exposure.
As for your symptoms, herpes doen't behave at all like what you describe. The location is wrong; although recurrent herpes can be somewhat apart from the genitals, like thigh or buttock, the initial infection almost always is directly on the most exposed parts, in this case your penis. And herpes would never cause a single painless bump of this sort. It sounds like you had a pimple -- and of course the thighs are common sites for pimples.
So my advice is to not worry at all about herpes or other STDs. You don't need testing for it, and if you have a regular sex partner, you can safely continue your usual sexual practices without fear of transmitting HSV.
I hope this has helped. Best wishes-- HHH, MD
