Some men go 'too quick'
Some men jump the gun too fast and get disqualified. A real artist is not afraid to daub his hands in the paint that he is using.
It is your hand that picks up the brush first, so men, use your hands before you use your brush.
I think that you are saying that some men do not practise foreplay. They are very anxious to do the actual sexual intercourse and they leave their partners unsatisfied because they ejaculate too soon.
As you put it, a good artist uses his hands before he uses his brush.
