It's good for all involved thinking so. As being on edge works so well for me as do I find more pleasure in giving than receiving. So I kind of relate a bit, as being TS myself on female hormones, I for one, never felt comfortable using the thing between my legs
Giving sexual pleasure instead of receiving is enhanced I think if the receiver of the pleasure enjoys making the imbalance as extreme as she is prepared to go. That's why I love women who can multiple orgasm: it makes it so hot when she insists on many but still sends him home having had none.
Permanent chastity or the threat of it could definitely make a man do things he never thought he would. Just when he believes he's been driven to his limits, he'll get pushed further.
Yes, it's amazing the things a guy said he'd never do but does when faced with that alternative. And there are women out there prepared to push to find those things ... good on them!
