If you finger a girl you should take your time. Don’t rush it, but build up the tension slowly. The more she longs for your fingers between her legs, the greater the result when you finally touch her inner lips and clitoris.
1.      Start with kissing, most girls enjoy this greatly. While you kiss you can stroke her back, arms and buttocks. Next you may touch her breasts. Most girls like you to pay attention to their whole body and not just to their genitals.
2.      When she gets in the mood caress the area around her genitals first, like her belly and inner thighs. Wait with touching her vulva till she spreads her legs and almost pushes her vulva into your hands. This is called the ‘grasshopper technique’, making her vulva leap.
3.      To let tension build up even further you can first touch her vulva through her undies before you let your hand slip inside. Let her long for your hands on her naked flesh before you undress her.
