I don't suppose it counts as "escorts" as such but I see working girls at a parlour every now and again. I've been nine times and seen seven different girls since May 2011, one of whom was just trying to make it in porn. She's had a fair bit of work done and is almost unrecognizable now from when I saw her, which was between boob jobs 2 and 3 (of an eventual 4). She has gone on to work for Shebang and Killergram, which is surreal to say the least.
Through going to this place, I've experienced sexual activities/positions that I've never done with girlfriends, and also had sex with different ethnicities/body types than I had previously. I've also met some genuinely interesting and sweet girls, which is a bonus once the baby wipes hit the bin. For the time being whenever I visit the city, I expect I'll find time for a punt. Make hay while the sun shines, I don't expect finding fanny-for-sale quite as easy when I move to Tokyo.
