Compression squeezes definitely give the width your looking for. I did them for a month and got good width expansion, but as usual, I stopped lol. Clamp my penis, put a plate on top and bottom, then use a c-clamp to compress them, sit for 5-10 minutes then release, rest and massage, start over again. Very tough exercise if done this way. Will test your nerve real quick.
Any girth gained will help with stretching the vagina, whether depth or width. Depth is better because width can stretch and rip the pussy lips. Stops sex for days, ask me how I know😵. Compression will give the width and follow that with
SSJ'S. The best of both worlds brother.
I know what your trying to find out. The best answer; always go for depth and width. Your penis will expand where it is easiest, you have to make it go where you want. I gain on depth for example. Width is ok but I want more lol. I used to clamp and do downward bends, good for width and expansion, you can bend at the spot you want to increase. A technique that needs your full attention, you can and will hurt yourself if you don't be mindful.
