Depends on what you do... there is no risk of pregnency,only STDs,the only protection I can think of is being sure your partener dosen't have any...
Washing your hands for fingering. I know there is an oral condom. It reduces the risk of STIs via mouth and vice versa. You could use gloves, as well. They're pretty sexy, so I've heard. Just make sure they're the latex, no powder gloves. Washing and sterilizing toys after and before use is very important. Never share toys. And communication with your partner could be considered protection depending on what you're doing. For example, restraint of the hands. If they get numb, the person tied could tell partner. Always have great communication in whatever you're doing, even oral sex. That's all I can think of. I'm not an expert, nor have I ever been with anyone ever, but these are things that maybe you want to take into consideration? Meh. Hope that helps.
