In one way, you might say that the women selling their bodies are the cause for men cheating, but OTOH if there were no men who did cheat, we would all be out of business.
I don't think that paying escorts is somehow enabling us to do this, or that is a bad thing for everyone. Most certainly there are situations where a girl really does not want to be here in any way, shape, or form and does so only to get out of a tight spot. In those cases, some guys feel bad about having sex with them, but they feel good about being able to help her with her bills.
So no, it's not a "man" problem, or a problem at all for many. There are no absolutes when it concerns why people do what they do. Some women love this work, some like it, and some can't stand it. I would say, all of the above have been felt at one point or another in my time here, based on the client I was seeing. I love some, like some, and can't stand some. The latter, I simply don't see again, but not all women have that luxury. Many are forced to take every dime they can, just to get by and that leads to seeing guys that repulse them just for the money.
