Does my straight guy friend in college like me back?

So I am currently studying at a university and there is this guy that i met about a year and a half ago. We both played on our school's club lacrosse team He is awesome and we have been really good friends since the day we met. My friend also happens to be extremely good looking: 6'2, fairly fit, great smile.. I wouldn't go so far as to say that I am bi, but I also have no intention of living my life with one hand tied behind my back.. so I guess you can say I am open to new experiences. My friend flirts with me mainly when he's drunk at parties with me.. this can include frequent eye stares from across the room, him getting slightly jealous when I hook up with girls at these parties, frequent run ins with each other in the bathroom or by the bar that result in him trying to get me more drunk, and many other slight things that have accumulated over the past year and a half.. Also my friend has some slight gay tendencies when he is drunk... Ive seen him playing with others guys' hair, passing out on other guys' laps or shoulders(all his good friends), sending me snapchats of just him when he's drunk (lol idk but it was kinda weird), I have also never seen him hook up with another girl before either.. besides one time when I wasn't there.. That night I was in studying for what my lacrosse team considers to be the biggest night of the semester and everyone brings a date to this party (I couldn't go because i had a lot of exams the following week) My friend drunk texts me as I am studying in the library asking me for a condom and if he could have sex in my bedroom...i said yes and told him where they were.. and he continued drunk texting me wishing that i was there... I came back that night with no one in the room, but the used condom on the floor..(did he has sex with her? no clue and neither did he after he apologized for having sex and leaving a "maybe used?" condom in my room There has been so many other things that are just little, like when i friend requested him on a social network and he didn't accept it for another 2 weeks (even though i saw him multiple times in between then and he accepted other people within those 2 weeks), him becoming friends with the same girls i hook up with, but The eye contact is probably what i notice most.. he is always looking at me.. and I kinda wish he would just say something if he does like me. Lol I wouldn't say no. I honestly think he is one of the coolest people i have ever met, and i would pretty much be open to whatever. kinda dumb how people can't just say what they are thinking *I have also begun dating a girl, and he just happens to start dating a girl them same time.................. *I know these are small things, but you have to understand that we are on a sports team with majority of the guys being strictly straight and look down on someone being gay...so idk what everything means
