I have a dick which is only 4" erect I have 2 problems with it.. 1) I can't pull my foreskin over the head when erect, it is too tight.. How can I fix it? 2) There are dots on the base of the penis and on the underside. They are just like small white dots, you can only see them if you turn my penis upside down. And they are almost invisible, it is hard to even feel them.. Is this fine? I am a virgin, never gotten sucked/fucked lol.
