Any of them
Older or younger (by quite a bit). Not same-age, really.
I love older women, I have admired older women since high school and I started dating them shortly after high school. I had a 3 year live in relationship with a woman 17 years older then myself. If I could find the right older woman I would settle down with her if she would have me
For some reason I get along better with younger women who like older men. Probably because they don't have the baggage and can enjoy life. I've gone out with many women in my age group, even older. They're very unhappy because they're alone. Even if I start by saying let's just enjoy the evening and each other, five minutes later they're telling me their tales of woe.
I've tried both and I still am not sure.
I would go as low as 18, and possibly as high as 35. Generally I prefer younger, but it really isn't too big a deal.
Yes, around the same age.
It depends what is the age of the man, yonger men usually wanna date same age or older women, older men usually wanna date yonger woman.
