I agree with the interpretation that says it is about a couple who's happy but the girl is scared to commit because she learned that, if "it feels so good, it must be wrong". But I think it's not only this, since she's asking him not to follow her and not to impose on her his views of what she must want.
To me it seems as if the song says she's scared and she's wrong, but it doesn't mean he can force himself on her, because it would only make it all worse.
