If I ever was inclined, i'd have to say Lemmy Kilmister (Motorhead)

Rough, worn look, whom has experenced quite a few things in life

.... and to quote wikipedia...

"In a Channel 4 documentary called "Motörhead: Live Fast, Die Old", broadcast on August 22, 2005, it was claimed that Lemmy "had bedded" in excess of 2,000 women."

Not bad for a guy who's 62 years of age, and STILL touring!
