Hi, Actually I don't have any problem. But just want to know about this. So the question is, when I get the erection in penis I need to pull my foreskin and than I do masturbation. Is that okay? Or it should automatically pulled down once got the erection. I can not stretch foreskin too much. Because it has joint with the glance. I am not sure if I have asked it properly or not. Can you help me to answer on that if you getting idea about my question. Or can I send the pics of my penis so it can be better understandable. Waiting for response. Thanks.
