My husband is 19 years older than me and a lot of people took issues with that. They mistake older for old, (you can see in my profile how geriatric He looks at 43, lol). Its not an age fetish, I am attracted to a certain mental wiring that seems to be more common in older men, but I was once or twice attracted to younger men (2 and 3 years respectfully) who had that dominant mentality already prominent.
When we had met I pegged Him to be a lot younger (one of these days I am going to find that Dorian Grey picture He keeps in the attic, rotflmao). When He told me His real age, I was worried He was going to think I am too young so for a long time I left Him under the impression that I am a lot older than I truly was (I skipped grades so that was easy).
His age was just a fact, it had nothing to do with my attraction to Him. Age is just a number, more important is the maturity/personality of the partners. People told me it was unseemly for us to be together, but to me it would have been unseemly to break up with someone I already liked so much and with whom I have so much in common for the frivolous fact of the year He was born in. Of course a word of caution - once, it may be true love; but repeatedly - cradle chaser.
I have friends of all age groups, I get along with those who are older and those in my own age bracket just as well.
