I don't know, I think it depends on the woman. I have friends who married older men(i.e 12 to 17 years older than them). I genuinely think women age better than men. Lots of straight men neglect their appearance and Calista is a better woman than me. I'm sure looking at a pair of sagging testes is not sexy. One such friend, the age difference between her and her husband is 13 years(he's older). It was fine when she was 27 and he was 40. But now, when she's 45 and he's 58 its an issue now. He does not want to go anywhere, he wants to the same ole' things, doesn't want to try new things and wants to stay home most of the time. And we don't even what to go into their "non existent" sex life. Its actually more common than alot people think, men having "low libido" issues. Especially straight men. My friend is in best shape of her life, she has had a few non surgical/non evasive procedures(i.e peels and some fillers) but she looks great. The young guys hit on her way more than the men her husband's age. My other late 30 and early 40 something friends, all talk about their boring husbands who do want to do anything or try anything new. They basically start acting old in the forties. I'm looking for a person who is health conscience, in good shape, physically and mentally attractive to me. If I find a guy who is 5, 10 or 12 years young, I'll go for it. I would feel creepy being a serious relationship with a 23 year old when almost 41 years old. But I would date a 28 or 30 year old. I say go with the person who makes you feel good about yourself and that aids you in your journey in enjoying life.
