Is it normal for a guy to reject a girl because of the appearance of her vagina?

I had a strange talk with my best friend today about vaginas and how different they are. My male best friend said he would be with girls with a certain shaped vagina and said others gross him out.

Is this true? I’ve never even heard of men complaining about vaginas! Would a guy simply reject a future with someone after seeing her vagina?

Is there an uglier or a prettier vagina? What do men generally consider a pretty vagina?
