Many things from quiet times with no talking or no sound, just concentration, to more physical things that only is limited by your imagination. With the right toys and a few ropes and clasps you can do many things to your body.

Know what you absolutely won't do and start from there. Discuss this ahead of time if you already haven't.

Will you bind your legs to the bed and tease yourself to almost having an orgasm a few times and then without cumming stop because it is a punishment? Will you blindfold yourself and stand with your back to the wall with your tits sticking out so your Master knows he could whip them if he wanted. Could you whip them for him?

This is only a few of the so many, many things you could think of if you put your mind to it. Maybe that in itself could be a punishment by making you come up with things to use as a punishment. The possibilities are just unlimited.
