If you are talking covered lips (what I think you are referring to as pretty) like this:
Or exposed (messy) lips like this:
My problem is where have you got the idea covered is the pretty one? TV, magazines, advertising and the like, listening to those around you is just repeating what I have just said above and they are just repeating what they have been TOLD by the media is pretty. DONT BE A SHEEP.
Think for your self, shrug off the things implanted in your head by others.
I Personally LOVE a pussy with exposed lips, I think of it like this, would you rather see a rose bud or a rose, ROSE in bloom, for me in bloom any day of the week & twice on Sunday.
If you have always had a ROSE know YOU are the pretty one.
