Why do so many women like Pete?

He's whiny, entitled, rude and (according to Roger Sterling) balding prematurely. But women are all over him!

I'm at the start of season 6 and TWO women have expressed interest in, what, having an affair with him...why??

Okay - maybe the answer is ''keep on watching', but reciprocation has happened several times already in the series. He just strikes me as openly very slimy. I'm baffled.
