Is the guy I'm talking to too disgusting to date long-term?

I really like this guy I'm talking too, he's really cute, we've been talking for like four days. Before we decided to "talk" he was such a gentleman, super considerate and respectful. Now the problem is that he is so raunchy! The things he asks me are so inappropriate I doubt people who have been together for a long time are talking about it. I like him but I wonder if this is a bad sign, like a sign that he's gonna like, pardon my French but like..." hit it and quit it". I guess what I'm asking is, does he feel comfortable enough to talk about this stuff with me or am I of little importance to him? Is it so bad to want to be treated like a lady?
