Well, put me in the minority. Kim doesn't appeal to me at all. First, much of her is fake/enhanced (boobs, face, lipo, etc.). Second, that caboose is about 3 sizes too large and, considering she's about 5'-nothing, a wide base looks even wider. Third, she's been with a bunch of guys that I would not take seconds from (amen to the body condom comment). Fourth, she's just SO annoying and arrogant and downright stupid in so many things, don't think I could be enticed to even try. Fifth, judging from the 'accidental' sex tape, she's about as energetic as a coma patient in bed.
Now, Kourtney....? Yes, yes I would. Even though she checks several of the boxes above, she's >> Kim in my opinion. Khloe? Uh, no thank you. Probably the one with the most sense but the least amount of looks. The younger chicks, i.e. sluts in training? Nope. And why any of that clan makes a dime is beyond me. It's our generations Gabor family: famous for being famous without a lick of talent or brains.
