I sorta came out last night kinda maybe?

Not sure what I'm looking for from this but I felt like I had to share this somewhere.I am in grad school and last night I went out with a friend of mine who I've been getting closer with more recently (it's not that kinda story by the way). We were out looking for a girl for him to talk to in order build his self confidence since he had just been rejected by someone who he had been seeing for the past couple of weeks. While we were out he made a comment saying that we have to find a guy for me that night. I sort of dismissed it as a joke since I was kind of taken aback or thought he was perhaps talking to another friend that was with us who was actually out.However, more comments like that kept coming up ("this place is full of guys, I guess that's good for you") which I sort of played off and casually mentioned throughout the night that I thought some girls were cute.(as an aside, which might be relevant at this point, I haven't completely figured out my sexuality at this point and I'm not sure I ever will be able to define it. I just know that I'm attracted to and can want to be in a relationship with any type of gender, sex, race etc. Basically open to anything)Eventually he just asked me what type of guys I like, at which point I answered honestly but vaguely. I'm not sure if it was the alcohol, but I was surprised to find that I didn't ever directly deny or confront any of the comments he made. Maybe I just didn't want to lie anymoreBut the strangest part for me was this. I've known this friend for about 2 years and the topic of me sexuality has never come up in the slightest regard even once. In fact, I have never really talked about my sexuality with anyone in my life unless confronted and then I denied it thinking it was none of their business anyway. Not to mention, it's only been the last several months that we've become closer friends.The fact that he assumed this about me is comforting but also makes be a little anxious. Its good to know that he's believed me to be gay for however long and our friendship is unchanged (perhaps stronger now). However, as a very private person in general it makes me uneasy to think that people are discussing my personal life and I'm not sure if I'm ready for a lot of people to know. And word travels fast around this grad school.But yeah, I guess I'm out now. At least to him. Or I guess I was never really in?Again, not really expecting anything from this. Just had to get some thoughts out.
