I was always against going to groups for personal matters, that aren't addictions or mental illnesses. One could argue for AA and such, the feeling of obligation to a group and how that keeps one from drinking, but your sexuality is not an addiction that needs to be cured. I would stay away from groups, as they will only tell you tired, cliched things and seek to make you think the way they think. Why do you want to go to said group?
So kind of like a blind dating service :/
