"move or arrange oneself in a comfortable

and cozy position"

"# hold (a person or thing) close, as for affection, comfort, or warmth; "I cuddled the baby"
# a close and affectionate (and often prolonged) embrace"

You are probably doing it already.

It's not rocket science.  I very much like to cuddle.  I like to feel her warmth, her essance.

Typically one of us will be flat on their back...  the other will lie on their side facing, legs more on less intertwined...  a large amount of body contact.  

Often we'll roll into lying face to face, on our sides.  Full frontal contact, arms around each other, often I'll slip one leg between hers & she'll feel the pressure on her sex.  As we move there is some friction between us & things heat up from there.

how would you like it done to you?

I assume that since you are asking, you do enjoy cuddling.  Not every client likes to do so, and you are under no obligation to do so.

Just be sure that you are gentle and don't do anything offensive.  When in doubt, just ask her.

I, for one, like to put my arm around her neck as we lay face up and then skootch her over to me as we turn towards each other.  The other arm can be put to good use by caressing various parts of her back, thighs and buttocks.  This position can also allow for pleasant conversation or just some light kissing or nuzzling.

I'll suggest that you get a giant stuffed animal toy (largest Teddy bear you can find) and try cuddling it using your imagination to block out "fake stuffed toy" with "real warm person". See what positions you like and are comfortable with. Try not to "soil" the toy.

Maybe you're not a cuddler or don't like it? Don't worry about it. Or do you think she wants you to cuddle her and you're somehow obligated to do so? You're not.

If you're too cheap or embarrassed to buy a stuffed toy, just use a big pillow (drawn on face optional).
