As it says in the title, she (26F) loves it when I (30M) go hard and fast when we're having sex. I'm talking some serious slam fucking, borderline hate sex, like it's something out of a porno. She'll end up looking at me while we're in foreplay or slow penetrative sex and say "Use me" or something like that, which is usually the signal she wants me to go hard, deep, and rough.

So you can imagine how difficult it is to avoid cumming in these situations. I can build DnD characters in my head or think about Donald Trump for only so long before I eventually have to bust. I can never go for long and, frankly, I feel kind of disappointed in myself.

We've talked about it and I've aired my concerns with her. Unsurprisingly, she really likes the sense of being dominated, like it's a psychological thing. I'm not against it, but with how frequently she wants it like that it's making me doubt my stamina.

Any advice would be great. I'm already a pretty fit guy, lift three times a week, diet's pretty on point. I'd hate to resort to drugs or something but I'm resolved to try satisfying this kink for her if I can.

EDIT: I'm thankful for the suggestions towards toys and other means of domination, both of which I'll bring up to her, but I'm hoping to hear some ways I can last longer when going that hard. A more moderate pace is fine for me, but beyond that we have issues.
