@Ragman,
I'm famous to myself for falling in love with younger men. Also, older men. Anyway, men. I find they vary. One of the best was 19 when I was going on 22. Quite smart, also quite wise, and fifty years later an appreciated writer. I wasn't a dumb young woman, exactly, but of the two of us, he was the teacher not just about sex, but poetry, art, nature, science, music, culture in general..
Rules about age are often quite stupid.
Of the posts responding about Kelly's question, I'll pick Roger's response.
