Ok let me post this direct from your previous quote....
".the fact that it does lubricate is part of this process but it does lot make it a lubricant"
and you deliberately seemed to miss the point I said too. I did say that it's specific job may not be to lubricate, but as a by product IT DOES lubricate. I said that I have used precum as a lubricant for edging sessions of 2 hours and more. So just because it does not work for you does not mean this is the case for everyone.
So once again I repeat.... I agree with you that precum's primary function is NOT as a lubricant, however I do NOT agree with you that it doe not act as a lubricant at all, it DOES, it's just that this is a secondary accidental function.
