As taken from a popular advice column in a family publication:
Q: I recently made a big mistake and had sex with my husband’s friend. He was much more skilled than my man. Should I tell my husband this?
A: No. But it would be a good idea to try and teach him some of the love play techniques which the other guy used.
Maybe I’m late to this new development, but where did the columnists who encouraged people to be totally honest with their partners go? I think they were just conning us with this full disclosure bit and knew all along that truth causes more pain than lies.
