I am 40 plus and from experience I think ladies perform best in
their thirties ....(ie 30-35) not too old though..... at ard this
age... those ladies that I have met, they are good man.. experience
and have pretty high sex drive,.... those in their twenties are not
as good.... probably still shy and inexperience lar.... and those
above 35, starts to get weak and cannot really perform. ..... so I
personally feel that 30-35 is the best age
My personal best is with two ladies, one from singapore and one
from Jap.... apparently both are freinds and suggested a threesome
during one of my ONS hunts.
The experience was good one lady is 30 while the other is 32....
both are pretty experience (they are not prostitute) and definately
can perform man..... and i tell you the Jap lady sure knows how to
make a man feel like a real man man .... hahaha 
Just for you young punks out there who wants to get laid (ie get
lucky), U have to dress matured and try and look/behave old.
usually ladies go for older more mature guys.... maybe they also
subscribe to the fact that more mature males can perform better (ie
more experience).
