It has always been more acceptable for the man to be the older partner in a relationship. While it can be creepy depending on the situation (Courtney Stodden comes to mind), I have never thought it was any one else's business.
When the woman is the older partner, though, it seems that commenting is fair game. Why?
There is a 17 year difference between me and the guy I am currently seeing (I'm 44; he's 27). While most people don't notice a difference because we both look to be in our mid-thirties, people who know how old I am seem compelled to comment. The consensus is that I must be emotionally immature because guys are always more immature than their biological age. WTH?
It's not like I'm looking for a pat on the back or anything. I'm certainly not a cougar who specifically sought out a much younger man. I just want to understand the logic better so that I can have a better come back than "it's none of your business" I guess.
