1. If you don't know, don't do. Ie get some help. There are plenty of people out there who can advise you on how to do all this correctly.
2. Be sure you know your playmates limit. Make sure they know how to use it.
3. If you plan on using needles in your cock and ball torture session, or other medical instruments, they MUST be sterile. Not being sterile can cause nasty infections. Trust me on this.
4. If you tie up the cock or balls, be aware that it will restrict the blood flow. This is ok for a short period of time, but not too long. Too long and you can do perminant damage. Just keep a close eye on it.
5. One for the men here, it seems obvious, but make sure the old cock and balls are clean. Your playmate won't be too happy with a dirty cock. Indeed she may be even more harsh with the cock and ball torture for you if you dont, it's a sign of disrespect don't you know.
