He can go wherever is convenient for him in whatever area of the world he lives in. Amsterdam is convenient for Europe. Travel might be necessary because the laws vary by state and country. If he's waited 38 years he can wait a few more months for the black death to go away.That is not realistic. Hop on a plane to go somewhere is never an option. You have Covid, local crime issues of the area, suppose you don't go travelling, like travelling or can't afford to travel? Why pick Amsterdam and not the Philippines or Thailand where someone might use their JBW card and get laid for free?
How would you know that? Did you actually go there?
Of course I myself would never do such an imoral thing. I wouldn't go to Tijuana and pay 70$ to take a girl upstairs at Adela's or pay 20$ for a BJ in Vietnam either. Another place I wouldn't go is Cambodia.
