The closest male equivalent is a gigolo or boytoy.
p2: oh skunt, den she wun gold digger
While some gold diggers are males... they are overwhelmingly females since older wealthy women can't birth children which is a major stumbling block and deterrent to male gold digging.
Plus gold digging doesn't work as well for males since males don't have the power to seduce that females have. All a female has to do to become rich is poke a lonely rich man in the belly and her bills are paid.
If a male pokes a rich woman in the belly out of the blue... there is a chance he is going to prison for being a creepy sexually assaulting pervert. Its dangerous for males to gold dig for the same reason its dangerous for males to flirt in the work place.
Females are "predator paraonoid". That is why most gold diggers are not males. In order for males to gold dig they must be "creepy predators:" first.

Jessica: Hmm. I wonder where they got it from.
