A woman can spread her legs, 9 times out of 10 she will get love.
A man can pick up women, 1 out of 10 he will get love.
You're talking about being a slut, not a whore.
If you charge for love then you're a whore, regardless of how often you do it or with how many partners.
By the way, men can be gay and therefore have love with an equal number of partners in one sitting as any woman, as the refractory period doesn't really come into play.
Also, the act of love isn't defined by having an climax.
