I engaged in a 3-some with a married couple last night. During the encounter the condom broke. The head of my penis was covered, but everything beneath it was not. Is there an incredibly tangible risk of getting an STI, if they collectively had one? I have HSV-2. My concerns would be HIV primarily. Thank you in advance. Note that as soon as I noticed the condom broke I pulled out - I was in there maybe 15 seconds. I'm sure I am making a mountain out of a molehill, but I have never had a condom break.
