Regret would be starting to see escorts from such an early age, became a habit and then never bothered with dating.
Also long term exposure to escorts can make you view women in negative ways like just sex toys, can cause objectification
On the positive time from escorts I had sex with lots of good looking women from all over the world - Spain, Portugal, Brazil, Venezuela, England, Poland, Czech, Algeria, France, Holland, etc.
Where exactly are you supposed to find hot women from Brazil, Venezuela, Spain, etc when you are living in England the normal way?
Guess it is akin to restaurant Vs cooking yourself. Going to restaurants can be advantageous to try out lots of food from different places made my people that should have a higher level of cooking skills than you have yourself.
