I have one close friend, and after many years we started to experiment on a small scale with things of a sexual nature. Never went all the way...he identifies as straight. But this has been ongoing for a long time now...and it really only brought us closer to each other, and bonded us in a way that is quite unique. I have also crossed the line with two other friends, but in one-off incidents, (they also identify as straight), and same thing..bonded us in a closer way. So I have been lucky as these guys did not get "weirded out" and left running for cover from shame and guilt. lol
