Recurrent foreskin tears
I'm 23 and have had normal, painless masturbation for ~9 years. Over the last couple of months, I've started getting small tears in my foreskin. It heals after a few days, but then tears again.
Today it tore badly during masturbation (when I pulled it back, it felt like it was sticky and the foreskin was attached to the glans using an adhesive) and bled from several visible cracks (bled profusely and it stung when I splashed water on it). It was very painful initially, but the pain has now mostly settled. The foreskin is currently covering the glans, I can retract it when flaccid, and I can urinate normally.
I am very scared and don't know what's causing this
