I was actually just wondeirng about this myself, yesterday...

Mine also points STRAIGHT UP against my belly even when I'm am standing up (literally like a pole), when I am really turned on. It's also quite painful to move it past the horizontal...

This is also why I wear mine pointing up when I wear underwear (mostly briefs or jocks, sometimes boxer briefs) cos getting a hardon when it's pointing in with briefs on is sometimes quite painful and embarassing!
