Again you cannot go wrong with either one. For me just depends what mood I'm in.
Roughly my age but, if we like each other and have a long term relationship, it probably wouldn't matter. I often think women are more mature than men of the same age, so younger by 27% minimum and older by 20% maximum. Besides in my case, people think I'm 10 years younger than I am when they see me.
You cannot wrong with both. Truly. But I must admit as I gotten older, it's the younger women who do it for me which is ironic since when I was younger, it was older women who did for me.
I must admit the younger women with now? They fuck me into the ground. And maybe it's just who I am with but my experience is that the younger generation is much more experience then their counterparts from 20-30 years ago.
Older women with experience of life, who workout to keep their bodies fit and firm.
