My boyfriend's d*ck makes me sick?

My boyfriend's dick and balls are so gross. When he walks around naked or with them hanging out of his pants I can't even look. Plus it has such a bad odor and I hate giving him head, even after a shower. Is it odd to feel this way? He will also pick at them and like stretch his sack out and it makes me want to vomit. Or repeatedly beat his limp dick and go "unssss" and hold his breath and his face turns red. I want to get out of this relationship.
