Use a fresh condom for each partner who shares the toys. Use latex condoms only. Gloves recommended for fisting. They can be used for finger-fucking if you have cuts on your fingers and do not want to wear a glove. If a dam is not available, cut a condom lengthwise and open it out, or use a piece of household plastic wrap.
Lubricants Use plenty of lube when fucking or fisting.
Lube is fun, and the play possibilities are endless. If several people are sharing lube, use one which comes in a pump dispenser or give each person their own supply in a disposable paper cup. Some lubes contain a spermicide called Nonoxynol-9. This has been shown to kill HIV in laboratory tests and so some men like it as a back-up in case a condom breaks. On the other hand, it causes irritation in some men which may make the transmission of HIV easier.
