I am a man in my 50s. Sex with my partner ceased for quite a long period and during that time my foreskin would not fully pull back over my penis head. When the foreskin is pulled back it's as if it is fused to the head. Recently I have resumed having sex with my partner and on the first occasion I started bleeding at the point of the join between foreskin and head. I would therefore like some advice about remedying the problem.
