Hi Doc - A couple of days back i had a sexual encounter with a prostitute and this was the scenario.
She was rubbing her vagina over my penis and i was wearing a shorts without any protection, we never had penetrative sex and i ejaculated on my shorts. I am unsure if any of her vaginal secretions did happen to reach my pants. I did not change my pants for the next hour or so. Do you thing given the above scenario i should be worried of HIV transmission.
