<human>: I entered college this year and made a lot of new friends, but there are these 2 that are the best ones. We spent so much time together, go shopping, eat together every night, study together and talk a lot about all the things. One of these 2 friends live with me and the other (the gay) live near us and spend a lot of time here (he is here right now). The two came from the same city and are friends for some years.

The thing is, I had no idea he was gay, maybe just a little when we started going out together, but then I started thinking he was straight for sure. Last night we went to a club and me and the friend that lives with me felt asleep (too much drunk hehe), and we missed some times of the party. So a few hours ago I was looking at the gay's phone and I read a conversation of the two in whatsapp where the gay said he made a out with a guy (a gay friend of us that was there), and that was very good, and in the talk it seems like he already made out with other friend of us (gay too). 

I don't have anything against gays, but I felt really awkard when I read this, it's like I don't even know one of my best friends. I don't know what to do, if I talk to him, tell him that I know, talk to both of them (maybe the other is gay too)... I just don't know, I've already seen the both of them with girls... I had no idea of this. 

Some details:

* We make gay jokes all the time... Like "You're too sexy dude, I wanna take you to bed right now"

* We talk about what guys we thing are gays. We talk about relationships, everything...

* I'm not gay, not a bit. I like girls and girls only!

What should I do reddit???

Give me a shortened version of the text
<bot>: One of my best friends is gay (or bi) and I don't know if I tell him that I know or talk to him about this...
