Cover art for Touch Too Much lyrics by AC/DC

I think this song can be interpreted in two ways:

1.) A woman who has a larger sex drive then a man, which he calls "a touch too much" because it drives him insane. (Overstimulation, ie.)

2.) Also, it could be about a mans sexual fantasy/masturbation. If you look at the lyrics "It was one of those nights When you turned out the lights And everything comes into view" etc. that idea fits.
