No, I'm not saying it to be nice! :P It physically turns me on (don't make me describe the physical effects, please! ;)). And yes, I'm aware of the blocks and also secondary things that can come with it (like the head banging motion). Actually there is a video of a guy with a severe stutter giving a Tedx lecture and having severe blocks and head banging to get through them. But he was really confident (or so it seemed). And really hot. So, for me, that's part of the hotness too! Truth is, if you are uncomfortable about it most people will pick up on that and feel uncomfortable too - that's not just about stuttering, but pretty much any other situation. If you're comfortable about it and have a "hey, that's how I speak and I'm ok with it" attitude, then some people will pick up on it and feel cool about it. Not trying to say that it's easy... but a lot in life in general is about perceptions.
