Worried about my sexuality
Hello I'm 17 and I'm a guy .I think I have a problem.
I think my penis haven't grown enough.It is actually 11,5 cm when erect and 7cm when flaccid and its girth seems to me normal .I also think that I have PE since when I masturbate quickly I ejaculate within 2-3 minutes and when I masturbate slowly I ejaculoate within 9-12 minutes.I'm worried because the I am below the average values for such things and because my friends with who I talk a lot about these things they say that they are bigger than me and that the normal size is 15-16 cm.Am I OK ?What is going on with me?
