Disclaimers: "why would someone tell lies on the internet" and "possibly just LARP" but here's an allegedly real story I read one time:
>have severe phimosis
>hinders normal hygiene, let alone masturbation
>give up and get medical circumcision
>recover for a week or how long does it take
>realize can masturbate, go at it like monkey for few days
What's funny/ironic about this, the whole reason circumcision is so prevalent in the US is that it was thought to prevent masturbation, back in the days when it was thought to cause basically every negative health impact imaginable.
