Male Gay Friend May Want Threesome with Me??

Okay, so background information: I’ve been very close friends with this guy for a while now - let’s call him George. Well, George is very openly gay and has referred to himself as “the gayest” multiple times. He’s been a bit slutty in the past, but he’s been dating this guy from another college- let’s call him Paul - who is bisexual for several months now, and they’re both super serious about their relationship and are both two of the sweetest guys I’ve ever met. Saying that, sometimes George will notice how hot a guy is, and say something along the lines of “well, Paul did say he was game for threesomes.” None of that was very surprising. I started wondering after other things started getting said though.

Like I said, my friend insists that he’s completely gay, going so far as to say vaginas scare him. Then one night, we were with a couple of friends, and he super casually mentioned that he wanted to have sex with a woman, nearly causing me to choke on my drink. When we all turned to stare at him, he was like “what? I’m curious, and they do say to not knock it til you try it.” And someone made a joke about how he wouldn’t know what to do, and he said “Paul is bi, and he’s game for threesomes, so it wouldn’t be a big deal.” I had shelved the knowledge but he’s mentioned it a couple more times in the past month or so, a couple of times specifically to me. He also jokingly calls me his wife - which again isn’t strange because he occasionally refers to several of his female friends like that - but one time I joked that I’d have to leave him for Paul, and Paul immediately grinned and said “thruple?” A lot of the things I’ve noticed focus on George because I’m around him much more, but I’ve also gotten close with Paul to the point that they both confide in me stuff that they don’t tell the other.

Again, these little things didn’t really make me think much, but then they went on vacation together, and George apparently used some of my over-used vocabulary several times as a joke, Paul noticed and asked if he was poking fun of me, and George said “I’ve got to make it feel like her prescience is here with us.” George told me that the day they got back - I was across the country on a vacation of my own. I thought that may have been slightly odd, but not too much. Another thing is that one time I had fallen asleep in George’s bed while he was waiting on Paul to arrive to leave on their date, and when he got there, I started to extract myself to give them some time alone, but they told me I wasn’t bothering them. I ended up curling back up and talking to them, but George was getting pretty heavy with the PDA considering I was literally in the same bed as them, to the point that I eventually left because I felt like I was invading their alone time even though they told me multiple times that I didn’t have to leave since they’d be leaving soon anyways.

And then a few days ago, I was hanging out with George, and he says, “oh, Paul and I are going to go to a full nudity gay strip club if you want to come with us.” As far as I’m aware I’m the only one they’ve invited, and the club is about two hours away. I’ve never really been in a strip club, but it seems a bit odd that they’d invite me to go with them, and I’m starting to wonder if they’re preparing to ask if I’d like to have a threesome with them. I’m having a really hard time figuring out what exactly is going on, so I’d love some opinions of what anyone else thinks about the situation.
