I usually place my hands on the underside of my boyfriend's jaw, gently holding his face to mine. Other times I rest my hands on his shoulders, hold his hands, or just lift my face up to his. Also, I hold on to his upper arms. Usually I place my hands for support because he's taller than me and I need to tip toe to kiss him.
I go for the waist, back. depending on how it is going and she seems keen, I may go for a casual butt grab. I wish more girls grabbed butts too... I don't know why they seem to think that is only something guys do to women... or maybe I just have an ugly bum lol
