The Mystery of Urine

One of the things that surprised me when I started teaching was how little information most of my students had when entering my class. I taught college, so almost everyone was an adult, and even if they weren't, they were considered adults if they were taking a college class (an issue that came up when I was showing porn to my students, but that's a different blog entry).

So here we have a group of 30 adults, and only a small handful came with even the basic information required to operate as fully functional humans. One of the things that came up on a regular basis was the intricacies of women and their pee. This was way before we would talk about different kinks (where pee would come up again). This is simple anatomy.

Where does the pee come out of?

Most men and women had been told, or came to believe, that women pee from their vaginas. This was more than a simple misunderstanding between the words vagina and

vulva (the vagina being the opening and the canal leading to the cervix, and the vulva being the entire external structure, including the clitoris and labia). Many of them had never heard of a urethra. Some believed only men had urethras, and both the owners of vaginas and the visitors of them thought pee came through the vagina.

This led to some misunderstandings, especially among those who were more familiar with the penis. Men often thought you had to take out a tampon in order to pee. Some thought that because it was the same structure, you should be able to hold and release menstrual blood at will. Some believed that women would pee when they orgasm.

This one actually confused scientists as well. Women's sexuality has not been studied well, and one of the things that lacked understanding was female ejaculation, or squirting. Some women, when they are sexually excited or when they orgasm, experience a rush of fluid. There's a lot going on there, so we weren't sure exactly what was happening. In my 20 years of teaching, our understanding of it changed dramatically multiple times.

For some, this happens with G-spot stimulation. For others, clitoral stimulation is all that's needed. Here's what we think we know at this time. The clear, alkaline fluid is released by the Skene's glands. It's different from the usual vaginal fluids that often accompany sexual stimulation. It's also different from urine, but it can contain trace amounts of urine. The biggest factor is whether the person peed right before sex.

What we have learned from MRIs is that the fluid enters the bladder and then exits through the urethra. If there is little or no urine in the bladder, then very little urine is mixed with the ejaculate. If the bladder is full, you'll have ejaculate and urine all mixed together.

Many people who squirt on the reg say it feels like they have to pee in the middle of sex and will stop and try to pee. This is actually very difficult to do, and there may be no urine in the bladder, so they can't pee. It's quite a frustrating situation!

The good news is that once you understand this, you can make different decisions. First, have a very absorbent towel down to help with cleanup. Secondly, go for it! The fluid won't hurt you or cause any problems unless the person already has an STI (sexually transmitted infection). Let it fly and enjoy the wonders of the human body!
