Ah great question. Alot of people mess up here. Many think you tip based off of how good she was, this is FALSE. She has sex with so many guys of course she is experienced. Sex is relatve so some people like anal, some like rim jobs....you get the picture. The amount you tip her solely has to do with :

A) Was her price reasonable? If so tip about 5% (these are whores thats aalot team them)

B) Was she too fat/skinny? Most have some sort of eating disorder. If she wasnt too fat or skinny then tip her a little more.

C)Did she fondle your balls when giving you head? To me this is extrmely important. Its one of thoses things that most dont but the ones that do.....MAN! I tip 10% for that little number.

D) Do you think she gave you a(n) STD(s)? Whores are not the safest means of getting off but to some that adds some excitement. If you see some wierd rashes on her or see her sneazying or any other signs of disease DO NOT TIP. Actually this is great news if she did  because it gives you the opportunity to haggle down her prices if they were unreasonable.

E) Did she want to cuddle after? I love cuddling after and usually they will make you pay for that. If shes down for a free cuddle then by all means tip her another 5%
