"Guilty or robbed". I understand that feeling. Only I call it "No commitments". Hooking up is a fun activity, but after the incounter, one does feel a bit empty in the heart area. Guess that's where the "robbed" feeling comes from.
As for not being a drinker or user, I hear u on that, too. I don't drug & very, VERY seldom drink. With our people, that CAN be a problem. After giving it some thought, I think you will have as much luck finding a Gay/Bi Anarchist that doesn't drink or drug as U will finding a mate that won't eventually cheat. I suppose they ARE out there... somewhere. Hmmm... where would one even look for such a creature??? Ok, here's my guess. Protest & rallys. That seems like U'r best bet. Also, though I have my doubts, one might try the gatherings. Rainbow, or Burning Man. The pickings may be slim, but it's worth a shot. Besides, these are fun, educationale experiences.
Also, have U heard of a group called The Radical Fairies?? Again, these folks drink & drug, but it seems to be kept to a mild hobby. Fastinatting folks, too.
I know U'r feeling alone & lonely sometimes. But remember this, YOU ARE YUNG. Mentally focus on the kinda person U want & eventually, he will come U'r way. Just don't be SO focused that U have blinders on. Sometimes, quite offten really, true love is so NOT who U thought it would be. Be safe & good luck.
