Yeah I really doubt the "can't get a prostitute" thing. And I really would recommend him to get one tbh. Not having had sex well into your 20s takes a toll on most guys' confidence and becomes something you look up to too much. Just doing it that way takes the pressure off and make you realise it's not the huge thing you thought it was. Been there and done that :)

IMO there's nothing bad about seeing one. People make sex out to be a bigger thing than it is. Most of the sex workers I know also enjoy the work.
