many shapes of my cock

I’m a 40yr man. My penis is uncircumcised. I am very proud of my penis. It has always fascinated me with the many different shapes and sizes of it. I naturally have an innie, meaning it doesn’t hang out of my body. It grows anywhere from 4″ to 7″ when erected. Sometimes my head pops out of my foreskin and sometimes it doesn’t. I can always pull my skin back to pop it out but if I don’t I never know if it is or isn’t. At times my balls will hang and other times they dissappear. Does anyone else have a penis that does this?
