Yes, I have. Being touch starved for most of my life, I bit that bullet a few years ago. I've been "lucky" to have found a couple of very lovely workers which I've been compatible with, or at least they are very good at what they do and made me feel comfortable.
-We probably aren't in the same country, but I assume almost every place must have review sites for their online escorts. Check them.
-Be reasonable with your money. Do not blow a lot of it on a sex worker or escort.
-ALWAYS use protection. Yes, we are in a ctb forum, but unless you are deliberately looking to catch something annoying, always use protection.
-Some escorts have their own place, but preferably meet her at a hotel or a place where you are in control, and safe.
-These kinds of situations are hit-or-miss. You don't really know if you're gonna feel comfortable with that person. It's a risk.
-Be respectful, be clean. They are human beings too and don't have to tolerate bad habits just because you're paying them.
And most important:
-This is just a temporary solution. Do not fall in love. They are just being nice with you because you are paying them. Even I, being as lonely as I am, have understood that and never committed that kind of mistake.
