I'm older than your spouse, so take this for what it is worth.
IF I was single, and I met a 23 year old who:
-didn't have daddy issues.
-didn't have granddaddy issues.
-who was self assured, capable, kind, self supporting, sexy, smart, mature, and emotionally well adjusted.
-who found me attractive physically and emotionally.
-who was sexually skilled and mature in their approach to sexual activity.
-who was the oldest person available with all the above characteristics and there was no likelihood after the plague that I'd meet anyone older with the same characteristics.
I would certainly consider a relationship with her, both physically and emotionally.
The only problem is, I was 23 once, and I have children who are around that age, so I have no trouble remembering what it is like to be that age...and I know better...so it is going to take a plague worse than coronavirus to get me there.
I'm done raising kids and I don't believe in magical pussy.
But, that is just me.
I also don't clean my guns when they are loaded, so I would consider myself "risk averse".
Plus, I have an uncle who married a woman that age, when he was around 50, and then his brother met and married her mother.
So, my uncle was married to his niece by marriage and his stepfather in law was his brother and his sister in law was his mother in law.
It is just fucking crazy.
