In my experience WL's think different, they do not consider having sex with multiple guys as cheating even though they have BF/husband/partner, I have met lots of WL's who are in serious relationship but once in a while pop into brothels to fulfill their fantasies or to get away from their reality as they miss having sex with multiple guys, most of them do it to make some extra money to buy either LV/Gucci/Prada crap and some do it because they like being WL once in a while.
If you are single it is easy to fall in love with WL's or ML's as they give you intimate sensual feeling and you would fantasise being with them once you are back home.
