Age gap jokes

I know people take the age gap seriously but it's getting ridiculous

For example as a twenty-two year old I'll sometimes bring twenty-one year olds to the bar with me and it's nothing but mean and insensitive comments like they're too young to drink, and where'd you find 20 of them?

I'm 27, my BF is 37. Is 10 years too much of an age gap?

'cause his son is 17 and really hot.
