With regular scripts for like SLR videos I have a mixed experience. During the experience I regularly feel a burning sensation around the head. When I climax I am very sore afterwards, especially around the prostate area. I also look older days afterwards, like a lot of energy has drained from my body. I think it has to do with the amount of friction I experience from the handy. I tried loosening the strap and I am using a lot of lube, but there is still a lot of friction. I use the extra true grip sleeve (which I think is the gen1 regular sleeve?). Does anybody have any tips for a softer experience?

Edit: a contributing factor might be that I'm uncircumcised and not used to 'raw' contact between the head and the sleeve.
