You dont want something too intense that will fatigue the penis, so keep it simple.
I would do a light pump session lasting 5-15 minutes, and then some clamped edging to get the new expansion fully hard, and engorged.
Keep a
cock ring on at the base, so it remains fuller.
If you got something like Viagra, pop that for a girth session so its rock solid in the pump, and when you clamp.
Good for when you know sex is going to occur in around 30 minutes post workout, but dont overdo the pumping i.e fluid, and fatigue.
If you got a sex session in mind the next day, then you can spend more time in the pump doing
5x5x3 using something like the silisleeve to keep fluid at bay, and afterwards a
siliring to keep the expansion.
