In my opinion, yes at 30 some women may not be able to compete with 18yr olds because of the fact that some have had kids and with childbirth goes your body.
Yes men unlike women at 30 or 40, hell if its in the DR (and you have money)an 80yr old man can get an 18yr old.
But let's stay focus here, (men) by their mid's to late 20's their sexual drive is gone.............you may have yourself an 18yr old but thats because you need her to finish you off...........by this age you cannot handle a woman (not a girl) who is in her primes sexually. So while you hang around with your 18yr old, developing a beer belly and going bald showing your little trophy around while others just turn around and know exactly why that girl is with you; women in their 30's need to also find a younger man who is still in his prime and who can finish her off...not the other way around.
Something else very important that happens to women in their 30's is that they are no longer shy to express what she wants, so she will get total satisfaction. With that keep in mind that anyone that you have been with and has been under 30, has lied when she's told you, "yeah....wow....that's the spot"..................nooooooottttttttt.
30 and up is all about us!
And hey.....don't take this wrong
