Hmmmmm.....im not sure what youre asking or what the problem may be.
Is it the fact that he only wants a quickie after initially wanting more?
Is it the monetary amount hes willing to part with thats the issue. (I think youre saying he wanted to see you at 150, but now only wants to see you at tge rate of 60)
Or is it the fact that youre going to waste a good condom, on a 10m romp? (Just being silly with that one

)
Are you being a dick, no. It sounds as if there are certain things you will & wont do...and hes asking for something youre uncomfortable with. Id just let him know that.
