Mighty Sparrow: This is a great question. It's also probably one of the hardest to answer. I've found that a lot of men can PE 5 days straight (hence 5 on, 2 off), whereas some men need at least one day of rest in between.
The best thing you can do is watch your PIs/body clues and let them guide how long you should rest. If you are getting hard erections and everything seems healthy, then you may only need 24 hours of rest.
Hope this helps,
