I've seen the 2 - 3 times a week thing being average loads too, Norwegianpoly. It's something that I think causes lots of anxiety. People who like loads more sex than that then sometimes beat themselves up about being overly sexual or have counsellors who tell them they are addicts.
People who like loads less sex can be similarly down because they also are told there is something wrong with them - repressed or lacking in testosterone or something.
The thing is that with average numbers, it's perfectly possible that nobody at all has sex 2 - 3 times per week. For instance, if I asked 100 people how often they have sex and 5 of them said 21 times a week, 5 said 14 times a week, 10 said 7 times a week, 20 said once a week, 30 said once every 4 weeks, 20 said once a week and 10 said that they never have sex, the average of that survey would be 2.72 times a week which then might lead me to report that people have sex 2 - 3 times a week on average.
That is true but not a single person gave 2 or 3 times a week as an answer. In fact, in my survey there are as many people never having sex as there are having sex 2 or 3 times a day.
To my mind it's more sensible to concentrate on the people I want to related to as individuals. If I like sex twice a day then it might be hard for me to be in a monogamous relationship with somebody who likes sex once a year. Similarly, if I don't every want to have sex, I'd probably be unhappy with a partner who wanted me to have sex once a month even if it was a poly relationship and they had other partners to use up most of their once a week sex drive.
I hate to see people being pathologised simply on the basis of their desire for sex - especially as it can and does change even within the same individual over time.
