7 Things you should never tell people about your relationship

7. When your partner has a smell, taste, penis size (whatever) that you didn’t expect.

When you first start seeing someone, it’s common for both men and women to dish details to their friends about their partner’s body, says Marin.

After all, what woman hasn’t had a rowdy conversation with her girlfriends detailing her latest hookup? But if the guy is someone you could potentially see yourself dating long-term, you may want to pause, she says.

“Your friends are going to eventually meet him, and your partner would probably be horrified he ever found out you shared this really personal information,” says Marin.

Now, that’s not to say you can’t say anything — he’d probably be stoked if you were vague and simply bragged on his skills a bit — but if it’s something that could potentially embarrass him or that he’s already insecure about (like having a smaller penis, for example), keep it to yourself.
