I think older women, 30 to 40 are the hotest.
Here's why 18-25 yr old women are preferable to a 40yr old. even for you:
18-25 yr old women will eventually become 30. So you can enjoy their company for a decade, maybe two. But a 30-40 yr woman will never be 30-40 yr old again. Next stop 50.
By the time they are 50 they are really hott.
