You would have to ask them. And, of course, they would lie. Even if they have less sex than their wives ...
What is all this nonsense about Polish guys being coy little virgins? Have never heard such b**locks in all my life! They are so very up-front, and up for it. They really are. The difference is: they get girlfriends at 14 as well, but are much more careful. Then they get married at 20, and they have lots of kids. And lots of sex.
So instead of, like the Brits, stumbling around drunk and stupid and getting into all sorts of trouble, they are at home, saving money, feeling secure because they have nice kids sleeping in their cots, and they (the parents ...) having frequent sex in the bathroom. That is how it works.
When I first went to Poland, I sat in a street cafe and gawped at the sheer volume of sexy guys walking down the street. Then someone pointed out that there was only one problem with them: they were all married. True. And having sex.
My verdict: Polish guys are highly-sexed. They are usually pretty fit, in all respects. They generally have more sex that their British counterparts. More sex ... but with one person. Which is actually the better kind of sex. And, because they are sexually confident, they are sexier men to be around. Even if married.
