Not mine - my DH.
About 6 years ago, he started cycling to work. We had done a few easy bike rides together in the summer, so this was not completely out of the blue. He wanted to get fit and save a few quid on the travelling expenses.
He's 49 and quite fit. We've always been fairly active - long walks, a little swimming, that sort of thing.
In the last years DH has become increasingly into the cycling, encouraged by a similar group at work. The problem is that the more he does, the less he's interested in sex. We've discussed it and he says he just doesn't think about sex when he's doing lots of cycling. It's not a huge problem for me, as I have a fairly low sex drive, but I'm curious to know if this is a common side effect of lots of exercise?
As a guide, in the summer, he's riding 200+ miles a week, mostly too and from work, some at lunchtimes, too.
