I found out my best friends are probably gay.

So the only people I consider "real friends" are probably gay. Them being gay is no problem for me at all. I love them yes. On a mental level. However, now where I'm 21 and they realised im in no way interested in a gay relationship or physical stuff they have lost interest. I came to this conclusion because i left the old "girly" me behind and im becoming a man now where i'm 21. So in retrospective i probably had a real gay vibe cause I were very introverted, skinny and a bit female looking. I have changed drastically over the years. It's pretty obvious to me now that they just had me as their friend cause they thought im gay. It's kinda sad for me to see them just smoking weed and vegetating at home all day long. How should i deal with this? I have no real friend anymore outside of family that i can just talk with and do sports with. All 3 of them tried several times to make a sexual move on me and I was way too naive and just kinda took it as a joke and pushed it out of my mind and ignored it. Any advice?
