Help! My Boyfriend’s Dad Keeps Bragging About How Much Sex His Son Had Before He Dated Me.

Dear Prudence,

Before meeting me, my boyfriend Dan slept around. He has always been upfront, and I don’t begrudge him his past. What’s weird is how often his father, Jack, brings up Dan’s flings. I’m guessing he enjoys bragging about Dan’s virility and maybe even gets a kick out of having an audience. I’ve asked Jack to make it stop, but things still slip out. Is this a normal thing for fathers to do? Jack also opines about the sexiness of Dan’s ex-girlfriends. I don’t know what to make of that either.
