@fesshole Every year or so I'm reminded of a friend working as a doctor, who told me he once received a patient and her husband who both lamented infertility and extreme pain during sex, while the woman also lamented urinary incontinence.
The visit showed that the husband penetrated her in the urethra, rather than the vagina.
I can't even start to imagine HOW that happened the first time, nor the absolute, inconceivable pain.
That was Italy in the '90s, btw. Talk about sex ed failures.
