Are sugar mommies as common as sugar daddies?
Question inspired by @AlongCameCindy's question Guys would you lose respect for a girl if you knew she had a "sugar daddy"? .
Sugar mommies are the opposite gender version of sugar daddies - older women who engaged with younger men for companionship and intimacy in exchange for money.
Frankly, I personally witnessed only two of these relationships, in contrast with the more numerous cases of sugar daddies.
