I would recommend putting one arm around her shoulders. The other arm you can leave at your own side. This is not a two hands position.
On their hands?
Yes, you should always wash your hands before fingering a girl this prevents pregnancy (if you have previously have sperm on your hands) and also STI's. You should also wash your hands after fingering a girl, its more hygienic.
Sperm should not come in contact with your hands if you are trying to get a girl pregnant. Sperm should enter the female's vagina during ejaculation while having sex.
be happy for them
Take a dump on his chest.
I see nothing wrong with holding hands. HOLDING HANDS WITH A GIRL IS NOT WRONG. BUT THE HOLDING SHOULD NOT EXCEED THE HAND.
around her waist
I think it should be when you have a 'chest' and you need one. I need to start wearing one and I'm 10.
It just means she's probably into you, and she wants or wished the hug would last longer.
put your hands in the air and dance with her. but look cool
girls should give the first hand job
That depends on the size of the girls breast and chest measurments.
