Whether or not it is "gay" is an opinion. People have different ideas about sexuality.

If you are not ready to talk about it with him, you might want to hold off on doing it. I am not going to ask him for you or give you a script of what to say. You know him better than we do, so you would be a better judge of how to bring that up with him. If you are really ready to do it, and are ready to do that with him, then you should be ready to talk about it. Only you can decide exactly how to do that. You can hint or just come out with it. It's up to you, what you know about him, how open he is about that stuff, and if you think he would be offended or uncomfortable. There are a lot of variables to consider in deciding just how to bring it up, and you know more about all of them than we do.

There is nothing wrong with that and it is no ones opinion to think its "gay" as the previous posted stated. I know of a guy who did this and he was not gay or bisexual. And to this day is not attracted to men, its just something he experimented with. I'd just make sure your comfortable asking/mentioning it to him.

That's not entirely accurate if I understand you correctly. I only point it out because people actually do define sexuality in many different ways. I am not saying that I disagree with you in general, or that I would call it "gay." My point is that what is and is not "gay" might differ depending on who you ask. So it actually is a matter of opinion.

Now, if you meant to say "it is no one's business" or something like that, then I would certainly agree. If it's something he wants to do, and if he really feel ready to do it, then I think he should go for it. I don't think anything is wrong with it by any means. I don't think he should care what other people think. I just wanted to let him know that he might get a variety of answers for whether or not it is "gay."
