As always I can only say YMMV - After a lifetime of self indulgence I can honestly say you pays your money and you takes your chances. Age, ethnicity etc don't count for much. Attitude and chemistry count for a whole lot. I love to fuck. If you happen to like me and we have a great time that's my idea of time well spent. If you don't like me or you're just having a bad day and you really aren't into it then too bad for me. I do my best to give a girl a good time an that's about all a guy can do. Generally speaking it helps if you love women - they kinda get that you know?
Oh and BTW I've had mindblowing sex for thirty bucks, shitty sex for two fifty and everything in between. I can't say about the higher priced gals 'cause that's outta my budget (I doan drive no Ferrari eitha) but if I had to guess, I'd guess I've had as good or better for far less.
