when it comes to women, there is more then just sex, let say instead, "attraction to women"? Besides, how you imagine for a man "over 30" and married, having sex left and right for a sake for comparison for LF poll? Try that and see for how long you going to STAY married!
well, in my late 20s I was attracted to women 36-41, as said above "girls are just girls" and never attracted me...
now i am 37 and still attracted to ruffly the same age group, maybe with -1 or -2 years shift, 35-40; but now they are my age .
later on, mostlikely, i would prefer the same age group too; essentially, IMHO, the best of women, matured and experienced on one end and no signs of decay or tiredness life, from another...
