There is a distinction between edging and “ballooning”. Edging, is basically getting to the edge of ejaculation, and kegeling and/or stopping stimulation before cumming.
Ballooning is actually getting to the edge, changing the location of stimulation and “ballooning”. There is a thread called, (I think), “ballooning, sweet rewards” or similar, by Werner Ashford. His thread will help you understand the difference.
I think ballooning after a routine will help solidify the potential gain from the workout. Edging will absolutely help with ejaculation control during sex. (that is a good thing by itself!)
Paraphrased: It is not the critic who counts: The credit belongs to the man in the arena, whose face is marred by dust and sweat and blood, who strives valiantly, who errs and comes up short again and again, who, at the best, knows the triumph of high achievement, and who, at the worst, if he fails, at least he fails while daring greatly, so that his place shall never be with those cold and timid souls who knew neither victory nor defeat.
