What is the male version of a "strumpet"?

I've often heard a particularly lascivious gentleman referred to as a lecher, from lechery.
But this has no "professional" connotation, so is prolly not the male version of strumpet (unless strumpet is being used in the colloquial, amateur sense as Helen pointed out). Just like some folks might refer to a woman who has a reputation for being loose as a real whore, even though there's no formal, professional, monetary exchange involved.


Lecher \Lech"er\, n. [OE. lechur, lechour, OF. lecheor, lecheur,
gormand, glutton, libertine, parasite, fr. lechier to lick,
F. l['e]cher; of Teutonic origin. See Lick.]
A man given to lewdness; one addicted, in an excessive
degree, to the indulgence of sexual desire, or to illicit
commerce with women.
