I have a closed tip of my foreskin at the tip of my penis, i am doing the stretching exercises for the tip to loosen out, i had read somewhere that if we use a cream with betamethanosol while stretching it will help, but when i apply that cream the whole area gets too slippery to stretch so i have started stretching normally and applying the cream after the stretch , but i don't know if it helps.

Please suggest if this is this right way to go about this thing, or if there are some other way which i am missing that may help me for phimosis. Thanks.
