lol interesting thread. I've had phases really. Senior year in high school it was almost daily with random people since I was single then. I took a year off after to 'find myself', so I limited it to around 2 partners, and during that time it was probably once per week. First 2 years of undergrad it was around 4 - 5 times a week with several people. After that point I settled down and it's been 3 - 4 times a week with my lady for the remainder of my undergraduate studies. When I started grad school it was probably only one week each quarter since I'm in another country now. But during that week me make up for the other 11 weeks.
I seem less interested in the pleasures of the flesh the older I get - either that or I'm getting to busy to think about the stuff.
