How can I deal with my friends always trying to set me up on dates?

My friends keep trying to set me up with other gay guys. Ever since high school I have had the same friends from theatre, they accepted me right away. They thought I was Gay, but I have never told them I’m not cuz I had no friends and having a good group of friends Made life more bearable. We are all in out 20’s now and they never seen me in a relationship, and even a long time ago when we first started hanging out one of my friends had a crush on me; which I turned him down cuz I said it would ruin our friendship. They have seen me make out with guys when we would go to the clubs, but it was mainly cuz I was drunk and was trying to be gay. Once I even let a guy I sorta knew blow me, but I couldn’t get hard cuz honestly I just wasn’t into it. I had these friends for so long they are like family and know how hurt they would be if I told them I might not be gay. They hate straight men esp. straight white men. At this point it’s even difficult to even consider trying to have sex with a girl cuz, most girls I know think of me as their gay best friend. Which I don’t mind because at least I get to be around them. I got another date with a guy my friend set me up with soon, and like before I’m probably gonna make up an excuse why i wasn’t into him. Then I will be called a picky *****, I just don’t know what to do. Should I just tell them I’m a gay Christian who is waiting for marriage?
