I'm 23.
Youngest: 18 (he would have to be superrrrr mature and special though)
Oldest: 40-45
I don't have hots for older men, but if he was really amazing then I wouldn't say no to him because he's 40. Overall, I am not that into people that much older or younger for that matter.
Youngest probably 17.
Oldest... Hmmm. Not that keen on the idea of dating someone much older than me, but if I met a man in his early thirties that I completely fall in love with it, then I'm not going to say no
Youngest: 18
Oldest: Ideally 29, but realistically I would go up to 39. I could date someone in their 40s if they looked young and we kept it hush, tho, but I prefer younger guys
Oldest is probably 30 for females (I don't want my wife too old to have kids) and like 35 for males (I don't want to date someone looking to settle down).
Youngest...well I like to be the young one so I wanna say 20 but if he's mature at 17-18 then whatever. Has to be my age for girls though, will never go for younger girls
