My penis size is 19 cm in length and 7 cm in width during erect stage. It is 13 cm in length and 5 cm in width during flaccid stage. I am really happy in my sexual life. My use to ejaculate within 7 to 8 minutes. During sex, I use to stretch my partner legs and I will insert my penis. Is that correct or, she should sit on me and jump on me? Which is medically correct. I have asked in many of my queries that I need to how to self exam my penis. I requested to say that elaborately step by step. But no one is saying me and I don't know why they are hesitated to say that. I am sexually healthy. But for my self satisfaction I wanted to know whether my penis is fit in all. Pls say me step by step.
