Well, indirectly, nothing, or at least "not much."
One of the things that does kick in is events that were current when you were AgeX.
For example, I lived in Hawaii when I was a teen, I was at school the day the Challenger exploded. There was an astronaut on board by the name of Ellison Onizuka who was from Hawaii, it was a really big deal at school - some of the students or teachers related in some way to the family as well as being something of a local (state) hero.
Meanwhile, my husband was four at the time.
So, as intelligent as he is, he simply has a hard time relating. Things like that sometimes make it a bit tough in the "mental stimulation" department... things that are important to him (age + nationality both come into play for us though) are not so much for me and vice-versa.
Joking (or maybe not) aside, as long there are different areas of common ground and a meeting of the minds, and not just purely physical (not really mine, or anyone else's business, but ...), then it could be viewed as a relationship that may not just be for the present, and short term.
The reason I think this, is because if so-called research and anecdotal evidence is to be believed, then a younger woman is still to reach her sexual peak at a time when an older man is already beyond his. This may or may not be a cause for concern, but may cause some incompatibility problems, at some point in the future.
For younger men the thought of an older woman, is often appealing, because of the above (I was no exception). The sad thing is, that as a man gets older - of a certain age - himself, this is no longer a relevant option.
The guy is divorcing, he is complaining about the amount of money he'll have to pay, and now he got a twinkie (If she exist, she is not with you for your cute eyes.... If your personnality here match the one outside in the real world.... ) Next story here will be about how is ex found out and try to screw him up more...
He could have gone for a Porsch to get his midlife crisis our of his system but he loves too much the attention he gets here about his sex life...
More you talk about it, less the chance that it does actually happen...
This is the most cosmetically enhanced thread I've seen on the forum yet. Half of the replies have been deleted, including many from the OP, and it had even been closed. Now it's been cleaned up and opened again and yet the replies again are heading down the same road as last night.
Dating a girl younger than 10 years is a criminal offence in most countries, Bertrand... I think it is fair to say that most people here wouldn't either.
