<human>: Sup?

Now that that's out of the way, I'm having a bit of an issue and it's one I've never had before. I really like this guy I'm dating, he's cute, smartish, nice enough etc., but I think we are not compatible sex wise. 

He is very rough and even when I requested gentle, he wasn't really able to comply? at first I thought he didn't know his own strength but it seems more like he gets lost in the moment and goes back to what he is comfortable with which is just... way to hard for me, especially if he's doing it for like an hour. It's also one thing if the main event is rough, but all the foreplay was more painful then playful. I've had really 
rough sex and recovered/liked it, but the way this guy pulls on me is just such a turn off, I don't even want to kiss him because he bites. 

Any ways I feel like I should break up with him because it's not like I can/want to retrain him to my own personal wavelength + I'm sure there is someone who can handle it I'm just not her, but is there a way to open up communication about this at all? He's really sweet. 

Also if I do break up with him is there a way of being honest without hurting his feelings? so he knows it was a compatibility issue, not a flaw? 

I thought about putting this in /r/sex but i thought it might be more of a communication issue.

<bot>: Dating a guy who is too rough in bed for me, should I try to talk about it, and/or can I end it with dignity?
