The same reason 100% of women list "traveling" as one of their interests even if the furthest they've ever gone from home is the next county over.
They get bored *very* easily, and anything that represents something bigger than the zip code they were born in is an adventure and automatically better. Ergo, let it put penis in them and now they can say they've "dated" a guy from [insert non-local place] to their girlfriends and watch them gush with jealousy. Quite honestly, it's very demonic, and I don't use that word often.
