There are seemingly no videos or explanations anywhere that show how to get the Silicap on. Even the video supplied in this forum just magically have the Silicap attached which leaves me dubious.
I haven't used my SiliCap in ages. Tossed that poor thing somewhere the world beyond. The cap is essentially a barrier to prevent accidental blistering from high vacuum pressure in the past. However, the reality is, you don't need the cap. After using the cap for a few weeks, I noticed that with proper fitting and suction between the base of the glans, the connecting sleeves, and the vacuum cup, the cap was not needed. Noticed how I highlight the world "sleeves". A dual layering of the sleeves between the base of the glans and the cup makes a world of difference. A wrap around the base of the glans before you put on the sleeves make a massive world of difference. You can read through the personal logs and discussions on how to use the SiliStretcher effectively without the cap.
I have tried every which way that I could possibly think and the best I can achieve it it resulting in looking like a poorly fitted beanie hat hitting atop of the gland, after thumbing it in like a flaccid penis into a poorly fitted condom. Needless to say, it doesn't work, and if I use the device when it's like this, it will result in blistering, bruising and the like.
The one single failure point is the bleed hole at the top of the cap. The hole should have been larger, around 1mm. The new cap has less than 0.25mm of a hole. Not enough to bleed the air trapped between the glans and the inner layer of the cap. The old trick we used to do was to keep the penis slightly erect, put on the cap, shove the glans with the cap far in, and then put on the sleeves. The newer trick the brothers used is much better, with one less messy step.
