I'm definitely straight-acting 100% and not out to any family or friends as bi. I live with a number of roommates in a house, whom I had only fist met before moving in with them about two weeks beforehand, so I'm obviously not out to any of them either and I plan on keeping it that way.

Here's the story. We threw a party and a number of my roommates friends from their hometown were here visiting. One guy from out of town came over, it was my first time meeting him and he turned 21 that day. We hung out for a good part of the night, and were both pretty drunk. He was also on a dose of acid and I had taken some molly. Once the party started dying down, we were trying to play Golden Tee (yes, the old school golf game you see in bars, we have one in our house) but couldn't figure out how to turn it on, so I asked if he wanted to play GTA5 instead. We went in my room and played for a while, I can't remember quite how long. While we were chilling, smoking, and playing I was getting some very indirect gay vibes from him, even though as far as I knew, he was straight. He also didn't seem interested in the party or whatever else was going on outside my room. I even went out a couple of times to check things out and he stayed. After we kept playing awhile, my drunk horniness was definitely on full blast, and I started getting kinda touchy with him. (Nothing too crazy, he was in a chair and I was sitting on the floor, so I would lean my head over and rest on his leg/the chair for a min, I might have rested my hand on him for a split second longer than usual when grabbing the control or ipad) After awhile I couldn't hear anyone else talking outside my room, and I asked if he wanted to go to sleep. I wasn't entirely sure if he was planning on crashing at my house even (he was staying the weekend somewhere else) but I offered that he could stay in my room, and even though I didn't have an extra pillow, he stayed. So I turned the lights out, and it wasn't more than 10 minutes that they were out and I decided to move in a little closer to him. I was on my stomach and he was laying on his back. My hand brushed up against his thigh and I left it there. After a little while, he moved his leg closer to me so that more of my arm was touching it. After a little longer one of us moved even closer cause I could tell my hand was even closer to him, and kind of under his leg, like close to his gooch I guess. I don't think he was asleep because his breathing wasn't rhythmic and it actually sounded like he laughed a few times. So then I just went for it and started feeling his crotch through his jeans, I could tell he was hard. I started putting my mouth on his cock, sucking through the jeans, and then started to undo his belt. He hadn't said a word at all. I undid his jeans, unzipped his pants, put my hand in and grabbed his cock out. It was pitch black and his pants were still almost completely on, so I couldn't see his face, his cock or anything. I started sucking for what couldn't be more than 20 seconds, and then my stupid self started getting a little more touchy. I put my hand up his shirt and started feeling on his abs as I made out with his dick. It was at this point that he said, "relax dude," the first words he said since I turned the lights out. He didn't sound groggy like he had just woke up at that moment or anything, and since we had just went to "sleep" I have to assume that me unbuckling his pants and pulling his dick out would have woken him up. When he said "relax" i had no clue if he was referring to my hand going up his shirt or to the whole situation in general, so I asked (with my mouth still right next to his cock), "should I keep going" or something like that. I honestly can't remember if he replied or not, but I don't think he did because I'm pretty sure I asked twice. With that I rolled over, didn't even put his cock back in his pants or anything, and went back to sleep. He stayed the rest of the night in my room when he could have easily went in my roommates room (his friend from home) or the living room which was unoccupied. He left in the morning without saying anything (I know it was morning because I woke up when he left.)

Half of me is disappointed and kinda pissed because if I would have kept going it could have potentially been really hot. Part of me thinks it was probably the right thing to stop at that moment considering he had never explicitly told me he wanted it and we were both pretty fucked up. What's your opinions about this? What would you have done if you were me?

Also, I'm kind of thinking I want to add him on Facebook. He goes to a college about 2 hours away from me, and I think the only time I might see or talk to him again would be if he comes down for another weekend to visit my roommate. The catch is, as I said before, I can't have anyone, especially my roommates know that this happened. Even though I barely know him I can't really see him telling anyone, especially my roommate. I don't really want anything to come out of me adding him on Facebook, and I definitely don't think I would initiate a conversation, but I don't know. If he comes down again it could be either really fucking awkward, really normal (if he doesn't remember?), or really hot if we somehow potentially hooked up again. I think that depends on if I add him on Facebook and what happens if I do. What do you guys think? Is it worth any potential sexual encounter with him? What should I say about it to him, if anything?

tl;dr met a guy at my party, thought I was getting gay signals, went to bed, ended up moving in closer to him and eventually sucking him off until he told me to "relax" and then stopped because I wasn't sure what he meant or if he wanted me to keep going.
