My refractory time is pretty good(5 to 10 minutes between pops). I have no problem doing 2 pops in 1 hour since I started swimming on a regular basis. Sometimes I have to go the GYM to shower afterwords. A few years ago I would book a 2 hour to get 2 pops, not needed now.
I make sure that I pick ladies who are horny and like do multiple rounds also. It helps if the guy is attractive and does not have pot belly.
Now if a lady is not into doing that I don't push her. I will put in my review that she is not multiple pop.
The hard swimming workouts have helped me stretch out my hobby dollars.
