Because you would not let us put them inside you if you thought they looked like sad mushrooms.

I'm a now bisexual but formerly straight guy whose main attraction to men is their cock. This is something I've wondered, especially when I first got into them. First, I think it's the most visual indication of arousal that humans have. Nipples get hard and pussies get wet but cocks go from soft to hard and you know he's turned on (morning wood aside of course). They can also be so masculine. Last, the shape is made for penetration. You see a hard cock and you know it wants to push into someone.

Yes, I over thought it. But they are so damn hot.

As a bisexual woman, I have to admit that I find pussies more visually pleasing, that's not to say I find cocks unattractive, quite the opposite, a thick, smooth, hard cock is fucking hot. But a smooth, shiny innie is going to make my legs weak in a whole different way.

Good question. What makes them hot exactly?

This is certainly the right place to look at cocks.

Question is why. how?

I am not sure but a do agree with you!!

Perfect shape to grab. Perfect size to put in your mouth or in your ass. Soft as silk. Show how excited their owner is.
