Preventing Blisters While Packing Pump

Finally after a year or two of lurking and just learning I’ve joined the thundersplace family.

I’ve been trying focus on length and packing my pump which I can usually pack in 15-20 minutes.

Only around the last 20 minutes do I risk potential blisters on my glans. I do 3 sets of 20 minutes well lubricated in my 1.75 leluv I’m shooting for the 9 inch mark currently at 7.75-8.00 after pumping. I only use about 4hg because of the amount of pressure on my glans after packing.

Now on to my question what would you guys do to help prevent blisters? Believe I first got a blister from using a heating pad to hot but after that it became more of a regular occurrence.

I’ve seen members talk about a silicone glans cap with baby powder to help with that. Also does the putting water in the pump help with preventing water blisters? Any input is appreciated thanks for your time.
