Yes! This! I have never understood the concept of "well, you're just friends so you shouldn't be doing x, y and z", or "well, if we've had sex together this must mean that we are..." or whatever.
I strongly believe that relationships are what they are, and don't like putting boxes around them. Terms like "friend", "lover", "partner" are descriptive, rather that prescriptive, and should in no way limit what that relationship is, or should be.
