Relationship Game: "I'm on my period"

I slip off the shoulder strap of her bra.
I squeeze her shoulder then the backs of my fingers rest on her chest. I turn over on top her and kiss her lower and lower on her chest until I take her nipple in my mouth.
She squirms and moans. She pulls my hair. Her back and body undulate and she eventually stops me.
"Stop, we can't" she half pleads half begs in the frustration of a girl that really wants sex but can't.
"I'm on my period."
She actually is so this isn't some shit test or LMR.
"I know. Just because we're not going to have sex doesn't mean I don't want to kiss you or touch you."
She smiles that smile of appreciate all women flash when you tell them what their girl heart wants to hear.

This, of course, with a girl you're just sleeping with, is not a move in the playbook. If you actually like the girl you're seeing (hey, for a lot of guys they seem incapable of a meaningful interaction with a grown woman with feelings and substance), this is part of nurturing a relationship. Your woman should feel safe and validated with you even when the possibility of sex is largely off the table.
There are times you're out with your girl and logistically you're not going to have sex on that park bench near the kids' bday party you're stuck at.
Does that mean you don't appreciate her whispering in your ear how much she wants to feel you on top of her or bending her over?

Of course not.
Don't be silly.
Throw your girl a bone while she's all uber emotional from her period and out of sorts hormonally.

 Good luck and happy hunting,
