If you want to get what you want, you need to give her what she wants, and that is no tangled mess when its over. So baby her! A shampoo is absolutely a great idea. And a cream rinse, and conditioner, and helping her comb it out and dry it. And lots of compliments on how beautiful she is, and how wonderful it is for her to treat you to a hairjob. And find out what kind of special sex she wants.

If she wears it long for you, and lets you have sex play with her hair, you are way ahead of most men in this world. Treat her like a princess, because if what you say is true, she is one.

Good luck.
