I've been rolling it around in my head for a little while now. As it is, my persona.. and any feline I draw.. do not have barbs, in fact I've always been a little hesitant to draw a zoomorphic penis of any type.. but I've thought of having "nice barbs". Let's face it, the male human penis doesn't really have all that much to satisfy girls who want to get off by intercourse alone, apart from the tip it's pretty much featureless. I was thinking about adding soft cartlage barbs, of course doing my best to make them as good looking as possible, but yes, I would love to get some feedback while I experiment with some sketches and study :3
