Some men have problems settling down with one woman. Others want more sex than their wives do. Men are not as emotionally involved as their wives, so for some this is a solution. Personally if I were in that committed relationship, I would hope my husband could talk to me about it before he went the prostitute route.
Because they are absolute jerks!!!!!! Men like that have no idea what real love or commitment is. All they care about are their obscene sexual pleasures. It is betrayal of the highest order in my opinion.
I think for some men it seems a viable safer alternative to having extramarital affairs. They can satisfy some aspects of "wanderlust" and not risk outside emotional entanglements that would certainly compromise a marriage. I don't necessarily approve, because it seems like a bandaid solution to a more complicated emotional issue -- with many risks, including STD risks in countries where prostitution is not legalized -- but as I grow older I can see the reasoning, at least.
These are the kind of times we are living in. The Bible warns us of the attitudes and heart conditions that would be prevalent during this time. (2 Timothy 3:1-5) But know this, that in the last days critical times hard to deal with will be here. 2?For men will be lovers of themselves, lovers of money, self-assuming, haughty, blasphemers, disobedient to parents, unthankful, disloyal, 3?having no natural affection, not open to any agreement, slanderers, without self-control, fierce, without love of goodness, 4?betrayers, headstrong, puffed up [with pride], lovers of pleasures rather than lovers of God, 5?having a form of godly devotion but proving false to its power; and from these turn away. However, the Bible also does tell us one other thing. “A man that is loving wisdom makes his father rejoice, but he that is having companionship with prostitutes destroys valuable things.” (Pr 29:3)
