I think I just like a vagina that I find visually attractive. I'm not sure I could point to a numbered picture on a chart to say what I define as attractive. It could be any of the examples, but its more based on the individual.
The most important factor to me is cleanliness. This just means clean, not odorless or anything. I have been with one woman whose cleanliness and natural body chemistry made it to where her pussy was completely odorless. It wasn't exactly a turn off, but it made me realize how important scent is when engaging in sexual activity.
