I had a few close calls!

For some people, it’s so tight that you can’t retract it even when flaccid.

If, after puberty, you can’t easily retract your foreskin over the head of your dick (it also shouldn’t hurt), you have a very unhygienic problem called phimosis.

It can be self cured with regular stretching but sometimes you will need a doctor to prescribe a steroid cream to assist with this, the worst cases can require circumcision.

New releases used to be £40 when I was a kid (twenty years ago), given inflation, £70 sounds not too bad.
