Foolishly I received oral from a guy (I'm a guy) unprotected this past Sunday. (I was on a roll with protected oral a well as protected anal but didn't protect with the oral this go around) It's now Thursday and I wanted to know when would I be out of the clear in regards to stds. Nothing as of yet - no burning or discharge or anything. Just curious. I didn't see any cold sores on his lip or anything. I haven't developed any cold sores. He sucked me for about 5 mins Then we just jacked off.
