Women have three holes so that when they get drunk, they can be carried home like a bowling ball.

Some people's children.... are male? did not have a human anatomy course in high school? were sheltered from learning about the human reproductive system? Really, ladies: when men think about your genitals, we tend to think about what we can put into them, not about what comes out of them. To a man who has lived in the United States, and grown in it's 'education' system, it's not unexpected that they (who have never had to experience a period, nor spent inordinate amounts of time watching women urinate) expect women to urinate through the big, obvious opening. The state of our education system is such that it is difficult to teach human anatomy and physiology, and understandably, the excretory process is typically not dealt with in any specific detail. Therefore, unless your boyfriend was a VERY curious child and his mother was very open, I find it hard to believe it could be expected for him to know exactly where your urethra is.
