I do like to fuck rough but only when a partner enjoys it. Most encounters begin with me on my back and a partner slowly sliding on so he controls how much he takes how soon. It's okay if he gets on and off several times before taking all of me or gets off and lies in a passive position while I slowly get deeper in him. It's all about communication.
Some guys need more time than others to take it all. It's part of the play. For myself sex is about pleasure, not pain. That said the line between pleasure and pain is different for different individuals. Some guys vocalize in what sounds like pain but don't want me to stop or slow down. Again it's all about communication.
One effective non-verbal communication is the Heisman--a hand or two hands pushing against my torso or thighs to slow me. It is so much fun to withdraw a little at that point and work that depth until he allows me to push past it.
So the answer is no I don't get frustrated. If a partner wants to stop I stop. But it's amazing how many want to start again and keep stopping and starting till I'm all the way in.
Additional: I long ago learned that a lube injector makes penetration much easier,
