Ok, so when i get an erection, my glands are fully covered. I can pull the skin back about halfway down, but not all the way. My question is...should I try more stretching to loosen the foreskin, or should I not stretch anymore since my glands are covered when erect? I'm afraid if i try more stretching, during intercourse it will be painful, but if i penetrate with the glands covered, it will be less painful. I don't know exactly which road to take. thanks!

Your question is nearly identical to the one in the previous thread. Note the answers there.
