In nearly four years of hobbying I have seen a whopping 8 providers. Most of my appointments are repeats among just a handful of women I really like. Not-before-seen women are a rarity -- like one or two a year.
But, see, even though what I just said is true; there are three factors that render it virtually meaningless.
1. It is not verifiable.
2. The average man has had sex with 6 women in his LIFE. So 8 in four years is highly promiscuous by ordinary standards. (And I'm not counting civies from before that.)
3. A guy only has to have sex one time with one woman to get every possible identifiable disease. He just has to have bad taste or bad luck.
