Rich WASPS are the hardest to bed and worst to deal with. Jewish American Princesses are also awful, especially if they are from the New York area. I can't stand them. Come to think of it, any woman from the New York City area is a b!+(#.
Asians are the easiest to get into bed, BY FAR, and are the sweetest. They do this little "I'm so innocent and you can't have me on the outside, but I'm so naughty and want you bad on the inside" kind of thing. I can see right through the act and they become putty in my hands. There is a difference by nationality, though.
Indonesians are the easiest if you speak the language (check) followed by Filipinas (check), Thais (check), Malaysians (check) (God, I love Malaysian girls), Hongkongese (Check), Mainland Chinese (check), Singaporeans (check), Japanese, Vietnamese (check), Koreans (sort of check) and Indians in that order. Koreans are a bit funny, in that their friendliness and hence ease of potentially having sex with, is inversely proportonal to their attractiveness. The really good looking Koreans are unapproachable. The ugly ones will follow you home. (I've only slept with a white-Korean mix that doesn't fit that profile, but I have had a Korean girl BJ due to bad timing for a date) I haven't slept with an Indian, but one did want to sleep with me. She outright asked if I would. I turned her down because she was too old (34) and not that pretty.
If you involve money, then the order becomes Thais, Filipinos, Indonesians... the rest are the same.
Mexicans (check) are just hoes that will sleep with anyone. I've tried one and I don't really care for them. They are not very intelligent and I don't like their outlook on life.
American black women and I don't usually get along, but I've "known" a Kenyan (check) and a girl from US VI (check) and dated once without having sex with girls from Tanzania, Ethiopia, and T&T. I could have bedded those too, but they just weren't my type; It doesn't always hold, but I try not to sleep with girls I don't actually like. The Tanzanian girl was very pretty, but 6'1" tall. Actually, I do have an American black e-pal right now I might sleep with; nice, pretty, slim, smart, not typical at all. She certainly wants me to. I might in a few weeks. Maybe I will add her to my girlfriend collection.
I haven't slept with an Eastern European, but a beautiful blonde Russian girl was pursing me one time, but I didn't trust her hygene. Maybe I will try some Russians some day; I think they are supposed to be easy if you are rich.
I hear Czech women are easy too, but I haven't met one.
Someone mentioned sorority girls. It depends on whether they are rich WASPS or JAPS. One of my gf's right now is in a sorority, but she is not rich and not Jewish. She is a nice girl with a raging sexual appetite.
