I do believe most people, who are uncut, keep their cock clean. However, I think it's the 10-20 percent who don't that give the wrong impression about uncut cocks. However, it's not just uncut guys. Honestly, I have encountered both. I have had two separate experiences where the guys cock was unclean. One was uncut, and the other was cut. And, both times I spit their cocks out. It was totally my fault though. Had alcohol (and the guys smoking cigs) not been involved, the cocks would never have gotten past my lips. I would have smelled it, it was that bad.
I have a real problem with guys, who have a date or a hook-up, to not shower and clean before hand. Seriously, why would you not? I have been in spur of the moment situations with guys before, and they have said, I wasn't planning on this happening, gonna take a quick shower first. Do you mind? Perfect. I think it should always be about mutual respect. Unfortunately, today, I don't believe there is a lot of respect going on.....
