What turns you off?

an uncircumsized penis would not be a deal breaker for me.

I think it might be for me. I've only seen one & I thought it looked like a mole. Had I known that before things got that far I never would have let them get that far.

Me too. I had the same scenario. When it's time to get naked, they already have a raging hard-on. Speaking for myself, I couldn't tell since he already had a boner.
It's after the fact when you're lying there in the afterglow, sweating like pigs, and you catch a glance and WTF is that??!!
Yep, I think it looks like a mole too.
That was 15 years ago...I don't think it would bother me now at all, as long as he has good hygine.
