I can actually give you a descent answer, because I in fact tend to go for older men, not so old they don't have their own teeth and hair, but I have always found 'older' men to be more interesting as people, probably because they have had more life experiences, and what's more I find some men actually get better looking with age, their features are more defined. I also from experience have noticed that older men, tend to chat me up more then my age group does, I don't know why, but its fact, I have had more older men flirt with me and let me know they find me attractive, then guys my own age. Now, I never imagined that I would ever date someone a lot older then me, (I just knew I kinda liked the older man better then the younger man in theory but didn't really want to practise it)
However, I am in fact now in a relationship with an older man, he is almost double my age, I am 24 and he is 42, and we have been together 3 years, we live together and next year we are getting married, a lot of my family thought that I will soon come to see the bad side of this, but they can see why I might be interested in an 'older' man, they thought this in the beginning, But since being with him, and my family getting to know him, they F***ING LOVE HIM, they like him more then me, and my mum didn't give him an easy ride, believe me. I know he is the one for me, and I wouldn;t ever trade him for a younger model, and it ain't about money either, we really only have enough to rent with, and ocassionally eat..lol (joking there, but we are getting by, not wealthy)
I can see how the 'reality' might settle in, but for me it never has, and I believe the reason for this is because, despite him being older, we both have experiences we still have to experience, neither of us have children and niether of us have been married (he had a very bad accident when he was in his younger years which held him back and he had to rebuild his life pretty much from scratch)
I won't deny that we have had issues on the marriage an children things, but not from not wanting them, and not wanting them together, its been more about whether or not we can afford it.
And while one day I might have to face that I could be on my own in my older years, I can live with that, knowing I at least got to be with him, and live some of his years with him.
