Bad hygiene

So I think it's time I break up with my boyfriend. This man has the worse hygiene and some other disgusting habits I'm bout over it. First off he doesn't brush his teeth (I basically have to ask him to brush them constantly when I'm over at his house) and bad dental hygiene is a huge turn off for me bc I don't like seeing crud on someone's teeth or smelling breathe that smells like the inside of an unscrubbed toilet. He doesn't clean his manhood off after we have sex and just lets mine and his juices sit on his junk (usually won't take a shower for a day or 2 after). He will wipe his nose on his blankets or with his hand and then wipe it on his shirt. We've been dating for only 6 months and its like all his nasty habits are coming out. I've talked to him many times about the brushing teeth thing and he just gets an attitude when I bring it up. Like I'm over all this. I've never dated someone so gross in my life.
