Great advice AndyJ, thank you.
I’ve been using a sports headband around the ring base to stop the burn, but I think I’ll invest in the thick foam weatherstripping tape you recommend. Sounds like a better long term solution.
I made some adjustments to my vac cup today, and I had a much better seal and less edema on my head.
1. Using a silicone cap over my head before going into the cup (I think the vendor just re-sold me a silicone toe cap)
2. Going into the cup 100% flaccid. Otherwise, blood will flow out during my extending session and break the seal
3. Filling the cup halfway with water before sealing it onto my head. Learned this from Perv at r/gettingbigger. It didn’t work for me initially since I had too large of a cup. I switched to the small size, and the water trick is working great now
I’m trying to extend 6+ hours per day, 5 days a week, for 3 months. I’m currently only 3 days in.
Then I’ll see if I’m actually gaining or not. To be extending this much, I am very interested in learning how to make it as comfortable as possible. I WFH and its been hard focusing on work while extending. My goal is to make putting on / wearing the extender a second nature while I work.
