“My Ex-Girlfriend Used To Do This In Bed. Can You Do It?”
Don’t Say: “My ex-girlfriend used to do this in bed. Can you do it?”
We’ve all got our sexual fetishes. There is no reason not to express those to your sexual partner. A guy just can’t say to his current lover that his former lover did a certain thing, it turned him on, and therefore he wants her to start doing it. Nothing kills the mood faster than making her think about your ex-girlfriend.
Instead Say: “Let’s try this in bed tonight.”
There is never any reason to mention your ex unless you are asked a specific question about her, or to yell a warning like “LOOK OUT! MY EX IS ABOUT TO CLUB YOU OVER THE HEAD WITH A BOWLING PIN!” Your current girl knows that sexual fetishes come from past experiences (why do you think she dresses you up like a construction worker during foreplay?) so just say “I’d like to try this” and leave it at that.
