Let me clarify that it’s only painful if I attempt to retract the foreskin when erect. When soft,I can retract it no problem and do so on a daily basis (cleaning during the shower). There’s no pain at all when I’m erect and the foreskin is loose and able to stretch/accomodate the penis when hard. It’s the act of trying to retract the foreskin below the head that’s painful. Last 20-30 years, this was never a problem. It’s like the opening of the foreskin has gotten a few millimetres smaller.

I don’t pull it back when jerking off, and only pull it back for sex. I’m not sure if the lack of sex in the last couple of years has caused this (only a handful of times this year, not much more the last couple of years. Before that, it was 1-2 times weekly).
