Hi whatami. I wanna address the issue that your cock foreskin
cannot pull back.
First is your foreskin opening too small to reveal your
dickhead? Meaning even when erected your foreskin still cannot
retract to reveal your dickhead, it may be the case of
phimosis. Read more on that.
Second, if you think your foreskin is not that small, not erect
can pull back but erect cannot. You might want to check the bottom
of your dickhead. There is a 'banjo string' which the term i
believe to be frenulum. It is attached to your foreskin via the
bottom of your dickhead. If it is too short, you cannot retract
your penis head, thus unable to reveal your penis. You might want
to read more on frenulum's breve in this case.
Why is this important because when you start to have sex, your
penis enter the vagina, the foreskin will be pushed back and for
your case, you will feel pain. You will not be able to enjoy
sex.
