Phimosis. Your relationship might be tight, but if your foreskin is, you've got 99 problems but a bitch ain't one. Often associated with balantis, and more commonly seen in children, phimosis is when the foreskin constricts around the head and refuses to budge. There are a bunch of surgical options to solve this problem, one of which is circumcision, but you probs won't need to go that far if you can handle a doctor trying to stretch your tip. Leave it to the professionals!
