Hey!
Im 17 years old and I have this question that I don't really feel like sharing with my family.
I have a problem pulling my penis skin back (sorry for bad english) when I have an erection - The skin would go back but quite hardly and it doesn't feel right.
However I can pull my skin back when my penis is not in erection and I have a habit of pulling my skin back whenever I go to the toilet and when I shower.
So I think it's taken care of hygiene very well but can this be a problem when having sex? (I can masturbate normally too). Is this a serious problem?

Thanks for your help!

That confused me a little but from what I interpreted it's just the foreskin pulling back when you have an erection... the head should be really smooth and the foreskin almost disappears.

If there is a issue, or problem or pain, have it checked out by your doctor. It is always better to be safe and know for sure

Well yeah I do have an issue :P It doesn't give me any pain or anything, I just don't know if that's OK..
And yeah - Its foreskin (couldn't find the right word before) that I can't pull back when I have an erection. I can pull it back normally when I don't have an erection though.

Check out this site... Functions of the Foreskin

And if it doesn't look like the pictures (don't worry, they are drawn pictures not photos) then should go to your doctors to make sure there isn't something that will be a problem :)

Ok I checked the photos and my penis looks like picture B in the fig. 9 when I have full erection. The skin doesn't go down all the way.. I can pull it back over like the half of my penis head but it won't go further(it's not comfortable if I go further).
Is this serious?

EDIT: oh and note that my penis looks like it's shown one those pictures when not in erect state. So it's only not right when I have erection.

You might not be getting a full erection?
I would be going to the doctor, there is nothing to be embarrassed about, they deal with those sorts of things all the time, if you don't want to tell your parents why you are going you could come up with another reason? I had a similar sort of problem, my mum knew but I told my dad it was something else to avoid embarrassment.
