Public Exposure: Whip It Out

Dick or ass or both. They're yours to whip out or yours to watch, depending on what you're packing. 

The "whip it out and jerk it off" guy is a different species than the "whip it out and let it hang" guy. If you're a penis scientist, the distinction is quite important to you.

If you're more a "oh wow he whipped it out, fuck that's hot" person, then science can go out the window.

Except for the scientist who unzips and opens his lab coat, all while wearing protective eye wear and black no-slip shoes. Add a pen in his front lab coat pocket and you see where I'm going with this.

So part of the pleasure of guys who show off is watching other people watch the guys who are showing off. Catching them looking. Definitely something to bond over, share a smile with, or if some guy freaks out over you catching him watching, then steer clear. Not a good sign when someone can't handle their attractions.

As for the naked guy on the beach, well not everyone is naked on that beach so it qualifies. Plus he's capturing his moment and sharing it beyond the beach. What a guy.
