For some time now I wanted to make a list for all those mangas in which sex is more or less purchasable. The list contains all kind of characters who sell their bodies - like hosts and prostitutes - this can be a one-time deal or they sell themselves regularly. But it also features men who have apparently normal jobs, but it's expected of them to provide some additional services of the bedroom variety. There is however at this point NO amv-actors in the list, as we already have them mixed-in with the showbiz list.
Uke on this list do not need to fulfill the club requirements - therefore there are also girly uke on this list. For more information check each list post.
Alphabetically sorted (number in brackets indicates the list number, where you'll find further info)
7. Bun from is the main character of Miyamoto Kano's Walker Universe. He used to prostitute himself in his wild young days. Stories of the Walker Universe can be found in the following mangas (all of course by Miyamoto Kano)
the uke-boy in chapter 5 is no stranger to the concept of prostitution
he's very young and therefore appears a bit girlish or childlike (especially standing next to his salariman seme), but he can also take the initiative and has had lots of sexual experience while the seme was a virgin
