Missed opportunity?

Hey gaybros, I'm a closeted bisexual (not that I need labels I just appreciate sex and sexiness male or female), but I've not yet physically acted on any guy on guy activities. While I've only had physical relationships with women, I do love me some gay porn and sharing photos with the gaybrosgonewild reddit community to relieve that side of my sexuality. I've always been interested in being physical with a guy but the opportunity has never arisen.Today at the lunch cafeteria at work I was eating a late lunch alone when I heard a conversation a couple of guys were having a few tables over. It was pretty quiet at this time, which I guess made it comfortable for them to openly talk about sex without being overheard. Even though they were being quiet I strained to hear them once I noticed what the conversation was about. They were redditors, or at the very least lurkers because they were talking about gaybrosgonewild.My interest was piqued, I popped my ears to make sure I could hear them; sure, spying is unethical but at this point I couldn't not listen. Then my heart skipped a beat and a chill went down my spine when I realized they were talking about a recent album I posted there in my rew red papi jock. (Recommend, very comfortable, decent support and reasonably priced) The hairs on my neck stood up when I heard one of them go into detail about eating my ass nice and slow, then the other chiming in they could gag me then take ramming my ass. This went on for a little while, each scenario just as tantalizing as the next to the point where sitting in at my booth rock hard.I'm fairly shy and self conscious, and love the positive attention and self esteem boost I've got on reddit, especially those dirty pms and kik conversations (including one really hot one where I was completely submissive and at my 'owners' whim). Every inch of me(especially a very specific 6 inches) told me to turn around and go up to them, introduce myself as the 'fuckable ass' they've been talking about. But I just froze there and by the time I got up they were gone and I never even saw what they looked like.Guys... straight, gay, curious.. I missed the boat, have the courage that I didn't have and avoid the regret I'm filled with now. Sigh...
