This isn't about PE, just penis in general

I'm new to this site and I don't know where to post so I am posting here. I am now going to reveal my 'problems', I would really appreciate any advice:

Hi, I am 18 years old, 5ft 7" tall and weigh about 70kg. My penis size when flaccid is about 3inches and my penis size when erect is about 6inches.

My main concern is my foreskin, when I pull it over the head I begin to feel pain coming from my frenulum which is stretching a lot. I am comfortable with it not being pulled back over the head but I was just wondering if it was a problem and what would girls think of it? The head also goes a darker red, is this a problem or should I just refrain from retracting it?

I also have a quite significant upwards curve but it causes me no problems, pain or discomfort. I am just worried if it is some sort of deformity or disease. Again I am worried what my girlfriend will think when she sees it.

How do I compare. Many thanks in advance.

P.S. Shall I upload pictures?
