Search Results: tell if he is gay

So, I went to a strip club with my friend and I gave her some space because she met a guy there and they seemed to be hitting it off pretty well. So I backed off, started talking to these two Irish brothers that approached me; I thought they were gay so I was laughing at all their jokes, we took shots together and all that. At the bar, there was this really handsome guy who could not keep his eyes off of me. A stripper approached me and asked if I wanted a private dance and the cute guy butted in and said that I did. Which at that point, I was laughing because I had to fend her off so she wouldn’t take my money. Anyway, this is what sparked our convo. He bought me a drink and later on that night, I had mixed whiskeys and vodkas and basically got really sick. I was very very very lucky to go home with this guy (my friend had talked to me earlier and asked if I felt safe enough to be left alone with the guy I met and I gave her the green flag to enjoy her night). He took care of me, he told me he carried me like a princess into his house, he took my shoes off, and I woke up with all of my clothes on, even my mini backpack was still on my back! I got up the next morning and showered and everything, and we hit it off pretty well. I ended up sleeping with him twice that day and then we ordered some food, and took a long nap. At which this point, I was extremely tired. He said he needed to get up and exercise and I said that I needed to call my friend and get home. I was in his T-Shirt and socks and he told me to keep them so I would have a reason to come back, but I put his shirt back in his laundry and kept the socks. When it was time to go, I didn’t kiss him goodbye, even though I think he lingered for one. And I didn’t ask for his number and neither did he! So my friend and I were thinking since I know his address and I possibly want to reconnect with him in the future, would it be weird to send him a letter with my phone number on it or should I just let this go?
