I see things the same way, depending of course on the definition of gaming.
The first thing I think about is: do I really want to game someone for my entire life? Fuck no!
In the long term run, everyone will have better or worst periods, that’s ok. It matters how you handle them. As long as you are (bluntly) honest about it, that’s pretty much all one should do.
Like: “baby, I’m focused to finish this and I’m not really in the mood for sex. most likely its going to be the same for the next week or so. I’ll fuck you when I can devour you”. I mean: things happen, what am I supposed to do in that situation: have sex with her to keep her, as an obligation? Do this and you’ll both lose: she’ll feel sex it’s not hot like usual, you’ don’t focus on what you really want. Trying to control the outcome in a long term relationship it’s just too much work.
On the other hand, if you are honest, and she gets upset because you’re focused on something else - well you got an even more important answer: it’s always going to be her way.
I love a saying I heard from DavidX: “My life is like a train: I can’t change directions. You are welcomed to hop on the train and if you don’t like the direction, feel free to hop off at the next station.” That’s what women want(in my experience): a man with a direction, who does not try to “please” her.
