I was watching a dude jerk off (on video) and as he was jerking off, his balls kept disappearing inside his body. I've seen this happen a lot, and know that its normal, but I just don't like it (asthetically). I wouldn't say no to someone just because their balls went up. I don't think my balls have been inside my body since they made their original appearance! Does anyone else have an opinion on this? Like it....dislike it....don't give a shit as long as they work?
