Hi! I'm 16 years old and I was wondering about the foreskin of my penis. I find discomfort when trying to pull back the foreskin past the head of my penis while erect. I am able to do so, it is just uncomfortable. This is especially annoying while trying to wash under the head of my penis. One time while watching porn, I noticed that other guys' foreskin are able to retract further than mine and with ease. It was the only time a really noticed and it had me wondering if it is OK or not that I am unable to retract my foreskin as far as them without starting to feel some sort of pain or discomfort. After doing research I read that I could have a short frenulum. Phimosis is also a possibility but I don't think that's what I have. I would like some insight on this please, such as if I should worry about this or not and if this could cause discomfort for sex and reduce pleasure. Thanks!
