I'm not up to speed on statistics for men masturbating with a condom, but my guess is that it would be fairly unusual.

But on the other hand, it's also unusual for partners in affair sex to use one.

Huge red flag, but you don't have a smoking gun yet. Educate yourself on your covert monitoring options and use the ones that are appropriate. If you do and he's cheating, you'll eventually catch him.

Sorry you're here.
