Penis is so beautiful. I have thousands of pics of them on my phone from Tumblr, including my own and I just love looking at them.
The only really ugly ones are the small skinny weird shaped ones

But average to big, I've never really seen a bad one
But on the other side of the coin, I know straight guys who half-admittedly say they don't like the looks of the vagina.

I think straight guys just like it for the sake of sex, but don't actually like looking at them.
