Depends on the Dom & the sub I guess. Some subs like to be well constricted, with a mile of rope or restrictive clothing & some are downright claustrophobic.

Any Dom/me worth their salt wouldn't harm a sub.
If you want to learn something about what constitutes a good Dom, I'd suggest checking this site out- www.submissiveloving.com/

A good place to learn a bit- Cerina is a little cynical, but with good reason I'd say.

Not sure if that answers your question?
