I agree with the general consensus that a WG stating she is sapiosexual is utter bollocks and just another marketing ploy. We are paying to have sex with them, whether they are attracted to punters or not is irrelevant.
However, I do believe that for civvies, sapiosexual is a real thing. I believe my current lover is one. There is no way in hell she would be attracted to me physically or even attracted to my "money". From most of my punts anyone can ascertain that I'm not loaded and try to go for the "economy" end of WGs.
So, at the risk of sounding up to my own arse I do believe that my lover is a true sapiosexual, either that or she's mad as a hatter to want to fuck me.
