Well, it sounds like you have lucked out on the sex workers who have taught you valuable lessons and raised your self esteem and commented positively on your looks and encouraged you to seek relationships that involve unpaid sex. So you basically received therapy from the sex workers, which is probably more than you paid for. However, I think you still need to retain a more conventional therapist who would prepare your for the ebb and flow of the dating scene (successes mixed in with rejections). I probably should not be saying it because I have not gone through it personally, but from seeing and hearing about the experiences of other people, having been rejected three times by age 18 is not uncommon. People process it and move on, and you cannot. So for that I would seek therapy and then start dating just as other people do. Whether you disengage from employing sex workers right now or gradually is probably not very important, provided that you do not face untoward legal consequences, practice safe sex, and can afford the services. But from your description of your encounters with sex workers, I am pretty positive that the women would absolutely enforce safe sex.

I am very surprised that the hookers experienced orgasms with you. I thought that it was not part of their job description. Good for you.
