I guess it's like everything, the first time you do it, you have doubts and nerves, and the more you do it, the more normal it becomes. I think the idea of several guys all demanding attention, and then one feels he's getting less attention that the others and complaining about it, sounds slightly intimidating, but maybe isn't as bad as you'd think it would be. If I see a cock I want to suck, but another I only want to stroke, does the guy not getting sucked become resentful. I guess I might just have to try it out and see.
