Hiii Im 22 years old boy .but still frenulum is attached to my glans (genital )(some thread like skin. When it is not erected I can be able to pull foreskin back fully but at the stage of erection. I can not pull it back after the glans. It cross the glans full not after that. It has tight foreskin as well. I think foreskin is more lengthier than my erect size as well. Im so confused.(my father said that it will automatically be well)
