Rough sex

So I'm not looking for judgement here so keep your comments to yourself if you disprove of my preferences. I enjoy rough sex. Like tie me up, leave bruises on my ass and my throat sore sex. I am totally submissive and want to feel controlled. My current boyfriend knows I'm submissive but I've never told him I rough I like it. He might pull my hair or choke me a little but that's it. Do any of you in longer term relationships have any advice on bringing it up to him? I don't want him to feel like he's not pleasing me, because he is. I just need it a little rougher for stress relief.
