I once dated a man who was the same age as my dad (within a few days!). I had no idea his age when I met him. (he turned out to be a sociopath, but that's a different issue)
I was in a long term relationship with a man 13 years older than I am. FBF is 13.5 years younger than I am; and CBF is 15.5 years younger than I am. Before FBF, my bf was 8 years younger than I am.
There are times and situations in life where the age difference can and might matter a lot; and times and situations where it matters not at all. I used to date a man a few years younger than I, and everyone who knew him, called him 'old man.'
It's no one's business but yours. You're not obligated to tell anyone the difference in your ages.
Love is that condition in which the happiness of another person is essential to your own...
