I'll also say that, regardless of the sexless state of my marriage, I have ZERO regrets about getting married. Aside from sex, my wife and I have had a great life, she takes very good care of me, is the mother of my children, has kept herself fit, and for many, many years our sex was good to excellent. Regardless of how great the Asian pussy is (and I really only go after Asian women these days), I'm not trading my wife in on a new model. If you're getting married on the basis of just sex, you are almost certainly getting married for the wrong reasons.
A wise man from these boards once opined: "Eventually, all pussy turns rancid". I have to agree with that. One day your sex kitten isn't going to be very sexy anymore, especially after menopause. If you are getting married, you may want to ask yourself if your marriage can withstand being without sex, because one day it may very well come to that. If the answer is no, then its probably best to rent instead of buy. If I found myself single tomorrow, no way I would get married again.
