off-road season

During a womens menstrual cycle, the man or women may suggest to the other they 'go off-road'.

This means to engage in anal sex in order to avoid having sex via the vagina during her period (bloody mess).

Many couples enjoy this alternative with the aid of a water-based lubricant.

If you want to be more romantic you can always ask in French would you like to "aller tout-terrain"?
