It's hard when it's hard. When a man is excited, he loses control of how big it gets, and where it points. Most men are too shy to share their erections with others. I find it exciting to see because every man is different. DRs will say every man is very similar to the next guy. I believe every man has their own markings that make them sexy. facial, chest, pubic, arm, leg hair. Make me HOT.
