I did say what you quoted in the OP, but I also said this.
While I'll admit, jailbait and up to 20 is probably my favorite age(which this thread was all about in the first place) range, I am attracted to girls my own age or a little older, but also that as you near 40, women become super attractive to me again.
So probably it boils down to Jailbait-a little above most people's regular standards-> Most attractive to me. A little younger-39->can still find a lot that are highly attractive to me, but not as many as in the aforementioned age range. 40-50(or even a little older if I find them attractive enough)->More attractive than my age range yet still less attractive than girls that are younger to me.
I don't know how I can spell this out any plainer, and none of this is a joke in this one. Most of the OP was in a joking manner, and so was the sometimes joke after his first inquiry.
But yes, if I am attracted to a girl, on top of sexual intercourse I would also rather have a relationship because I guess I'm a romantic? I don't want one night stands with my age range either nor do I want them if I dated a woman about 40. It's just not how I operate.
