heh heh! Just my 2 cents, but being some kind of musician does get you laid in my experience. I am a very mediocre musician (I have no "instinct" for music I play very "mathematically", but hey I enjoy the playing) and am not handsome by any means, but my guitar playing (sucky as it is) has got me (and the other members of my rather ad hoc band) laid regularly. I think of being somewhat good at music as a "hack" to take care of the getting laid part (serious relationships are a different story).. And to be somewhat at music (vs being really good at it) takes only a year or so of practice so it is a good investment. So if all you want to do is get laid without too much effort, picking up a musical instrument maybe worth your while. The guitar is easy (compared to, say, the violin). form some kind of band and play at parties.
As I said, I am not discounting or challenging your (menloparkbum's) experience. just my 2 cents. YMMV
Damn. I just started to teach myself piano...
