Straight guy [M] in a long term relationship with a girl [F]. Last week I went all the way with a guy [M] [M/M]

Kind of happened as a surprise to her and me. Well the other weekend my buddy was in town, and he is bisexual and he was in the mood to find some dick. So naturally we went to a gay bar. I was trying to be a good wing man while increasingly becoming more intoxicated. Eventually I approached a gorgeous looking guy and started conversation to see if he would be interested. Tall, very muscly, with a good smile. I chatted him up and told him my friend would be interested, and he responded by saying “well I was personally more interested in you.” I try to explain that I’m straight and have a girlfriend, he responds “well what’s one night just to make sure you’re not even a tiny bit gay?”

This is when drunk, horny me steps in. I’m a little flustered but after a bit he leans in for a quick peck, and I decide to make it a deeper kiss. And after that we start making out at the bar. I could feel my buddys shock across the room. He comes up and makes a joke like “I thought I would be the one getting dick tonight.” And tells us to get a room. The guy was only in town for a bit and luckily did have a hotel room a few blocks away.
