Rough sex or slow and sensual are both good provided everyone is having a good time. Rough is not the same as abusive, that is, it doesn't need to be done with the intention to hurt. I am not into the shame and destroy routine...it isn't sexy...it's just a power-trip and it's grotesque.
I've dated some women that, for one reason or another, really needed sex to be rough in order to satisfy them. There were a lot of moments of "Are you sure about this?" and frantic "YES GODDAMMIT!" replies.
Having not seen the scene yet I can't really comment whether it crosses the line.
