I personally have never been attracted to a man younger than ~45, not when I was 18, not now, 20 years later. Just a sexual preference.
So when you were a teenager, you were exclusively attracted to men over the age of 45?
You've never considered a man attractive unless he was at least in his mid 40s?
Each to their own, but I'd say that's a highly unusual preference.
Have met many very attractive men in that category, and most of my female friends seem to be in (very happy) relationships with 15+ age gaps too. It is quite common, from my perspective.
As I said above, on MN people always seem to know couples with massive age gaps. Of course the woman is younger, and of course, she is actually the more mature of the two and the relationships are always highly successful and a partnership of equals.
Statistically however, as again I've said above, relationships with a 15 year age gap are very rare. Not common at all.
Not quite sure what you are trying to gain by trying to explain my own experience to me.
Why are you making this about your 'experience'?
As I've said, I'm talking about statistics, which make it clear that young men aren't looking to shack up with blokes in their 50s. They just aren't.
