When you hold a girl, realize that you are holding a living human being in your arms, unless she is dead (that's different). You must be gentle and flexible otherwise your rigidity can hurt her in subtle ways, use her expressions to guide you through this. When you finally find the right way to hold a (living) girl; you will find out how to hold any girl. It's relatively easy to figure it out, it's absolutely not the same with every girl. Every encounter is different, even with the same (living girl).
For those cases where you are holding a dead girl...well, I can't say for sure; just remember to consider rigor mortise, tissue breakdown, and sudden bladder and rectal discharges. Sometimes things like that can BLOW up in your face. :P
