Unless it's just a fun, sexy, baggage-free throw-you-over-your-desk situation where nobody gets hurt at the end.5.

There's probably a reason no woman his age wants to date him. Defending your relationship will frequently ruin your friendships.

But experts seem to agree that in contemporary American society the potential harm to a young woman depends on both on her age and how big the age gap is with her partner.
