Hello My name is Utkarsh and I am 25 years old. When I try to remove my foreskin during masturbation it is painful and I do not try further but when my penis is not erect the foreskin can be removed easily. Even while having sex many a times the foreskin Is separated without any pain. So I am not confident if I'll be able to remove the foreskin during the act and what lubricants should I use to help.
