Always safety first Vanessa.
Clearly, you don't understand the attraction and the sexual rush from this stimulus, and that's okay. Like you said, there are many varied fetishes and kinks that exist, many that I don't understand either. And I would not chastise or condemn the majority of them. Most are basically harmless and victimless.
Too bad Minnesota is so far away, I'd ask you what you're doing friday night.
LOL
You'll never know until you've tried it at least one time with the right partner.
