Personally, I have no very defined model of what kind of female aestetic features/etnicity that attracts me, although I can see how this can be an advantage knowing excatly what you seek. Chances are you're more likely to get it, and I sure hope you'll grow old to, and with, to call your finer half ''my babuscha''
Yes, it's extremely important to know what you truly like. Took me some failed relationships and a divorce to figure it out. I consider myself lucky in the sense that the kind of women I like also like me back. Now if hair loss doesn't get in the way, I can find a nice women to settle down with. I am 35, so the clock is ticking.
