I live near a beach and some of my friends have. The phrase "You'll get sand in places you didn't know you have" is enough to convince me it's not worth it. Not to mention the tourists, cops, kids, etc. And that's just at night. And the beach is used for Asshole Break Ups - go at it a bit, pull out, cover the cock with sand, ram back in ... I'm surprised we haven't had any dead bodies out there due to that.
