Are men who cheat still sexually active with their wives?

It just depends on the individual. There are some that do and some that don't. There are some men that cheat because they cannot bear to see their wives doing dirty fantasies with them so they find someone else (or the wives won't do them), or men that do cheat because there is just nothing at home and it doesn't matter whether they have sex with their wives or not, then there are men that are in over drive and want their cake and eat it too and frankly lie to the wife and the mistress, and then there is the men that think they are looking for something better and in the process wreck what they wanted all along and had - the grass just isn't any greener.
