This is a truly difficult ethical dilemma. I thank God that my stutter is not severe enough that I have been able to have intimacy with a woman without paying. So I can’t exactly preach to you because I haven’t been in your unfortunate situation. But as a Christian I would say do not do this. The sex trade is a tragedy. Porn (with which I struggle immensely) prostitution and at a push FWB/hookups are soulless pits of hell for everyone involved. Participating is perpetuating misery. I understand that you’re already very miserable. But try at least to consider the systems that you would be reinforcing by paying for sex. (Very difficult when you’re horny!). There will (hopefully) come a time when you will be free from sexual desire. This will be a blessed relief.
