I once dated a man who had a very large urethra opening. The kind of large where you can't help but stare at it in surprise for a second before realizing that maybe you shouldn't be staring at it with a look of shock on your face. That sucker was BIG, man. I could probably have stuck my thumb up there, but I'm not into that kind of thing (NSFW).
I've never seen anything like it and quite honestly, hope I never do again. Not to be mean or anything, but it was really unattractive - like a big eye staring right at you. I remember catching a glimpse of pre-ejaculate fluid pouring out of there and thinking "EW, that's going to be in me in any second now".
My question is this: Why do some men have larger urethra openings than others? Does it get stretched? Or is it like ears and noses and it just comes (...) in different sizes?
Have you had experiences with larger than normal urethras?
