Is it normal for a woman to pay for a man's attention ?

I am a sexually active wealthy older woman. I do have very good luck finding younger handsome men to enjoy sexually, so I am not deprived. But, I also run into situations with some of the younger men who I enjoy who ask for money at times. I am able to pay them, that is not the issue, it is that at times, I am even more turned on when they ask me for a couple hundred dollars to "borrow" knowing they will never pay it back after an evening of sex. I have a thing for what some would call bad boys, 20 somethings who may have been hit hard by the economy recently and are either under employed or unemployed working blue collar jobs like construction, or other trades where money has become scarce. I have never said no when asked. I find the evening even more intense with the men I know will probably be asking for some dough after they have given me an intense evening of bad boy sex. I am pushing 60 and I have a sex drive that won't quit. I have the means to pay these men. Yet sometimes, I wonder if there is something wrong with me? I do know there are Gigolos and male escorts I could hire but there is something more exciting about a main stream sexy younger man asking for money after I "used' him for my needs.
