Don't think women are being so selective tbh
Evolution comes from survival of the fittest/strongest. Our gene pool is pretty poor now, don't think we've got much evolving left. If anything we're going backwards.
Nah, very few women choose who the father of their children will be based on their penis size.
If my school years taught me anything it's that we should evolve to keep our bits tucked into our bodies like those tribal people do so we don't suffer when kicked in the nuts.
