That, Adera, is something I asked myself as well.. going on a limb here, girls if you want to yell, please be my guest..
I can't see the fun in whoring either. But what if it is not about the actual deed, but about the result it gets? From almost everyone that posts here on forum, a good experience is what they are looking for, where there is pleasure shared by both, or all partners. I saw a banner of someone doing weekend sodomie and scored 57 in one weekend. That means it is about something else as passion or pleasure.. That is keeping score..
I imagine the ones demanding a fee for sex, as laughing in their fists after they collected the next fish, which allows them to spend or hord cash.. So I see it as a power rush.. And it is not uncommon that women use their sexuality to accomplish something... Without judging that in any way... That's another discussion..
I can't think of any other reason as this, or it being a fetish as Adera mentioned. Inthe end the motivation must go... once you've bought everything and are at the start of a new, payed for month of membership... why fuck for the moeny? fuck for the power-rush...
Ok, everyone can take aimat me now
