Uncircumsized anon here. Apparently when you get erect, your foreskin is supposed to go over the glans of the penis. Thing is, mine doesnt. As a matter of fact, I have problems pulling it over when Im not erect. Ive never managed to pull it over the glans without an excessive amount of lube whilst erect, and even then It wouldnt go all the way over; I could see 90% of the glans but never 100%. Ive been searching around but I cant figure out what I have. The internet says its supposed to be phimosis, but im pretty sure phimosis is when the foreskin is glued to the glans?

Are there strechting excersizes I could do, or do I need to snipsnap?
