The average British adult has supposedly had 10 sexual partners IIRC. But only a quarter of them have actually had 10 or more, so the more active ones are inflating the average (10 is the mean average, where you add up everyone's number of sexual partners and divide by the size of your sample). The median average (where you line everyone up from lowest to highest and pick the person in the middle) is 5.
If you do that with just women, the median drops to 4: with just men, it rises to 6. Presumably this means that the "average Joe" has one girlfriend/wife, three exes (bringing him up to 4), plus two one-night-stands or similar (which his female equivalent wouldn't have, as average women generally don't go for that). Punters wouldn't count in the median, as we are not in the middle of the range.
Interestingly, all the way up the scale, men have more sexual partners than women, until you get to the very top: the prostitutes, and a small number of nymphomaniac civilians (presumably these are the ones that "average Joe" managed to get off with a couple of times).
I'd include them in my count if it was safe to do so. If they "don't count", then other forms of casual sex shouldn't count either. And if you've had ten "meaningful and committed relationships", then you've had at least nine failed relationships, and suddenly that doesn't look too good.
Perhaps you could just count the ones who accepted a second booking from you, or the ones who contacted you afterwards and invited you back.
