I am 23 years old, I'd consider myself rational about most things, but this scares me absolutely shitless. I know that's dumb, but if someone like me is made extremely nervous about screwing with my method of reproducing, then that can indicate what other people are feeling.

Secondly, I see orgasm as a highly pressurised, highly tuned, intense thing. It feels like I'm straining every part of my balls to the limit when I'm doing this - if I had medical procedures down there, anything that could psychologically make me feel they were frail, that would utterly ruin it.
