hi im 16, i was having sex not long ago and my foreskin pulled down n killed i had to keep pushing it back up, i didnt even know it was supposed to come down, anyway ive read some forums saying that you can keep pullin it back to loosen the forskin n ive been doing that and its been getting easier and ive just noticed that the back of the penus cant fully go down because of a little what i think is a vein connecting to the tip of the penus
