feeling internal pain and not feeling "stretch" when stretching
hello guys,im having a problem with manual stretching,because when i do stretch(any direction),i hold my dick either midway of just behind the head(i have tried both),and what i feel is like if i were pinching an internal nerve,causing an internal pain,its worse when i stretch sideways(i use a strong grip),and i do not feel any type of stretch while doing it(but it works well when doing the rotating stretch),i have a foreskin and i retract it before pulling,bot i retract it only enough to discover the head,would i have to bring it ALL back?,bany advice?,thanks dudes
