Okay, now this one is funny!
Really, it depends on the drummer. I tend to think that guitarist get the girls (in everyband I've ever played in, the gtr player got mass trim).
However, the thing with drummers is that we have rhythm and stamina. If you are not a virgin, you've got to know what that means to a girl.
And drummers are usualy wild. After a gig, that adrenaline is still pumping, and (sweaty or not) you go out there hunting.
We single guys who play drums realize that the girls just saw us laying it down hard and heavy. We know that many girls will connect that to sexual thoughts...
A few drinks later, a hand on a thigh, and viola, horizontal refreshments!
Playing music in general brings in the chicks, and each postion has it's positives and negatives in this area, you just have to know what works for you.
But above all, don't let getting laid come between you and your band mates. That is most important, cuz tomorrow is another town, and a new show. Tonight is finite...
No get out there and pound 'em!
(BTW- Singers don't have much fun. On tour they can't drink or smoke much, and need to rest early, so they are usually back at the hotel when we drummers, bassist and guitarist are raging until the a.m.)
