Bottle foreskin stretching.

Hello I am new here my goal is to get extra long foreskins that hang well over the head feel this gives me better self-esteem when I am in the shower and sauna with others. Now has 4 cm foreskin. I use a bottle of wine that I heat with boiling water cools the top of the bottle and puts some of the foreskin into the bottle - gently cools the bottle and creates a strong suction that draws only the foreskin into the bottle and stretches pleasantly leaving the bottle between legs hanging a 20-30 minute time. This gives me a longer forehead. Others with similar experience ?
