<human>: Can you give me the gist of the text in a nutshell?

Hold on to your seats because things are about to sound conceited. I've been dating this man for almost two months now, and we made it official fairly recently. He's got a business degree from a fairly prestigious university, and a fairly good job. He's incredibly handsome, athletic, and driven. He treats me very well.

I love him. Until he opens his mouth. He mumbles, uses very childish language and litters his sentences with (like, dude, so, etc.), buys into conspiracy theories, doesn't really display any intellectual capacity beyond some general knowledge in his field (at this point in time I'm ashamed to say I probably know more about his field than he does), forgets things, makes stupid/awkward comments, has very immature views of the world, doesn't think before he speaks, has weak vocabulary, and in general I find being around him embarrassing. I'm not perfect myself and by no means would I ever say I am. I do have two science degrees and a fairly good background, I love to talk about anything interesting, I just don't feel like my boyfriend really understands anything I talk about, ever. We're not talking quantum physics or differential equations here, just things like how we see color and sometimes basic investment and financial stuff. I really haven't had an intellectual conversation with him that was actually interesting and not just general knowledge or pseudo-science.

This has escalated to a point where I don't want to sleep with him because it's a massive turnoff. I'll be really into him one minute but the moment he opens his mouth my libido deflates because he's either being cringe-worthy awkward or just dumb/poorly expressed.

How do I bring this problem up without bruising his ego? Should I even bring it up? Is there a way to "get over it"?
<bot>: My boyfriend is the most loving, selfless man on the planet but I can't stand how unintelligent and awkward he is. I have no idea how to deal with it.
