What is the ruling on committing acts of depravity with homosexuals, and how can one rid himself of such an act?

What you are doing has not reached the level of sodomy that necessitates the prescribed punishment (حد), but it is a precursor to sodomy. Along with the prohibitions it entails, its deviancy, and its violation of natural human disposition (فطرة), uncovering private parts (عورات) is religiously forbidden, even without desire.
