Josh is an exile in a foreign country and he (most likely) doesn't speak the native language. He's also an IT nerd in many ways which is not really conducive to hitting the clubs and scoring pussy. He's probably not as rich as to make up for that either. Worse, he could get in actual trouble very easily with local shady people if he starts courting the wrong woman.
So he needs to figure out a way to meet some nerdy chick that's into similar stuff as him, likes the web, shitposting, is politically right wing or at least tolerant to that, and that chick needs to be met somewhere online, but live in Serbia or willing to go there, as I guarantee you that the women you meet at the club are quite different.
Only a retard would accuse Josh of being a "virgin" considering the circumstances. I know the dating scene of the area very well, and it's a deeply depressing one, and most local women are basically just interested in you providing and/or making sure that they can leave the country and get to live in some nice suburban house in the US.
Also, imagine making an account to seethe about Null not fucking. Which I doubt it's the case, as he still has some money, and prostitutes/escorts are a thing here.
