Arguement sex can be a wonderful thing when it comes to drawing you near each other physically.
It doesn't hurt to tell her what you really want to do to her sexually either. Be explicit and expose your dirty Manly mind to her. You know what you want to do to her, so don't be shy in letting her know.
Although towards the end, my W and had problems communicating after or before sex, we never had issues communicating during sex. If you get the opportunity, talk dirty to her during sex, they love it. Be the freak in bed you know you want to be.
We can be sexually aggressive because it just feels natural to us. Don't be afraid to express your sexuality to her. We are dirty rotten horn dogs so stop trying to suppress it.
"It is curious that physical courage should be so common in the world and moral courage so rare." -Mark Twain
