So Mrs Webgoji is in the thralls of her sexual peak (which ain't all bad

), but as we've been married for 13 years, she wants to spice things up. That's cool by me, but there's one (well, maybe more than one) thing I'm having trouble with.
She wants me to be more dominant in the bedroom and get rough with her. That just goes against my whole personality and is very difficult for me. I've always been very respectful of her wants and needs, not wanting to hurt her either emotionally or physically, so when she wants me to throw her down and "ravage" her, it turns into a gentle controlled push and snuggle.
Talk about awkward.
I tend to slow down so I can make sure she has an orgasm before me. It's what I've done for 13 years now and can count the number of times on one hand that I've reached orgasm before her (and less than that when she didn't have an orgasm at all). This means I back down and am less forceful which she now wants.
Okay, enough rambling. So does anyone have any ideas how I can start to be more dominant in the bedroom? Just kind of a step-by-step thing so I can build my confidence up to be more aggressive without stopping myself? My concern over making sure she is pleased is making me have trouble pleasing her ... weird huh?
