i't wasn't a first for kouta, if you read Punch Up you will see the "Q-tip" scene ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
Yes, I believe the term for it is 'urethral sounding.' Like I said before though, you can't just shove a finger in your dick right off the bat. You'd have to work yourself up to be able to take a whole finger. They make instruments for that purpose. Its actually not just for men, though. Women can practice urethral sounding as well.
Haha, I was the same when I first discovered that this was something that people actually practice. I just didn't know what to think about it. To be honest, I still find the idea of it to be a bit unsettling, but it also kind of amazes me what the human body is capable of. I mean, you would think that something like that would hurt beyond imagination, and yet somehow people manage to make it pleasurable. I still wouldn't be too keen on trying it out for myself though, lol.
Did he finger his dickhole...?am i seeing things??
