You could do, yes. Talking about respect, though, sounds a bit more like a lecture than the rest of what you said, and the rest of it really is all right.

I was really just thinking you could leave out that bit about girls getting something they want, like this:

But even if a girl accepts on the basis of who she thinks you are, that's all right. It means she's getting something she's looking for, too, doesn't it? And I think you'll be able to tell, sooner or later, if that's all there is or if there might be something more meaningful in your, er, relationship.

That sounds more like you than the other, anywiz.
