Because the market doesnt demand it....if guys wanted to pay for sex AND have all the small tasks we dont have time for fucked up for us, we'd get a [nother] girlfriend.
Unless you are talking about an older single man, with a 7 figure salary / worth, that just wants arm candy, sex, and would also like a few things done to take care of him, to feel like he is in a relationship, without having to BE in a relationship, I dont see the purpose.
I've always wanted a hair cut and BJ experience, perhaps with a little light massage thrown in.
I used to have a single lady who was a barber in another state. Had her own shop (one chair), and yes, we discussed sex every now and then. I was stupid for not pursuing the notion, but with a little nice talk, I believe she would have drawn the blinds and BJ'd me right in the chair.
The only "Bundle" per se that I would be interested in would be...a long hot shower with the provider first followed by fucking everywhere in the room (bed, against the window, couch, desk etc.)..followed by a really good massage...now THAT would be a perfect "bundled" session IMO.
