late, but not to late! i've to spend more time into the lounge!!
just to answer your question, yes, everyone as a price, the one and only question is: how much!
but this wasn't your question, the question was how much I would ask for my wife. a good question.
i think 50-100.000€ could do the job - but this has to be found out if the money is on the table.
but, if you want to save money, i myself would turn around if you pay 20.000.
seriously: if you pay in front, i would, why not? i've never had gay sex, but damned, this is a lot of money!!
