I've given up on SB's less than 25.  Of course this number is relatively arbitrary (why 25?  Why not 24 or 26?), but that's not the point.  We all agree that SB's are notorious for flaking, having multiple issues, are prone to excuses, don't understand time management, and as someone on this board stated (paraphrasing) "easy to spook like a scared deer",...but it seems these annoying habits are magnified in the young set.  

otoh, I came out of semi-retirement and just bagged my third 18 yo.  Size 0 96lbs but amazing energy!  A total time waster: will text me a day later to say she feel asleep at her GF's house and couldn't text HaHa.  But, surprisingly in all other aspects very mature and fun to talk with.  Very mature with regard to money and never demanding... Nice girl, could have done much worse...but I wouldn't be surprised if she ghosts at any time.  lol

You keep banging the 26 to 34 year old group. If that's your sweet spot then see how many SB's it takes to get diabetes. :p

Just send those pesky 18-22 year old SB's with perky breasts and flat abs my way, please. I'll take care of them.

I honestly don't find that the 25-30+ age group is any better.  I dated one 26yo last year who was incredibly flaky, last minute cancellations, no shows, etc.  Fabulous in bed though so I put up with it. And the 2 18yo I dated last year were among the most reliable SBs I've ever had.  Right now I'm saying farewell to my 21yo SB who I've been seeing since she was 19 and is about to move out of state.  Super reliable girl.  And my current 22yo SB is driving me nuts with how flaky she is about making and keeping appointments. Just anectdotal evidence to be sure, but I don't see much benefit going with the ones in their late 20s, not if reliability and dependability is the goal.  As has been said before, all women are at least somewhat BSC.

...that flaky chicks ever grow out of it.  

True dat!

That is outstanding and enjoy.  I have not had such luck and because I like to incorporate my love of wine into BCD activities, 21 is as low as I've gone in the past.

A lot of it has to do with the race of a woman. Most white girls start showing signs of age at around 25 or so, most Asian girls have youthful skin and bodies all the way up to late thirties and sometimes beyond. I find Latinas and Black girls somewhere in between Asian and White girls. This is "generally" speaking of course, and like any other general statement like this one there are tons of exceptions.

Women retain the babyface characteristics as they age more than men.  Some ethnicities are just naturally closer to babyface characteristics so will retain those features for longer.

Asian women don't tend to get that "spread" that women of other nationalities seem to get. I am also sure you've heard "black don't crack" which also applies to a lesser degree to darker skin Latinas because just like Asians they aren't likely to develop wrinkles as they age.
