If you have 3 points to hang from it evens up the weight, I tried it years ago by piercing my nipples with curtain hooks and wrapping both the penis and testicles in a soft cloth. I attached ropes to all three points and was suspended off the ground for a short time in this way. It was a very stimulating experience. There was no long term ill effects. Just need to not rip anything off. That my comment, enjoy.

Don't do it alone and lock the doors. By chance you might make the mistake of getting yourself to swing free, but not be able to right yourself. If someone by chance walked in on you, it could be embarrassing to say the least. If they're an unfriendly like my sister-in-law she might take great advantage of the situation, and she would not be kind.
