Penis - Circumcision - How Long To Wait For Sex And Masturbation?

So I was circumcised 3 month ago... Let's not get into "why I did it".

I visited my doctor about a month ago and he said that everything is fine and Im gonna be okay.

But nothing is okay! He said that the swelling will go away in a month or two, but its been three month and a few days since I took my bandage off, and it is still swollen.. Not like it was two month ago but in this last month, NOTHING has changed.

On top of this problem I have this "other" problem. I dont know how to explain it properly but I didn't think that thats how my penis is going to look. And by that I mean that the skin is like "attached" to the glans (Hope I said it right).

I had stitches and the doctor said they will disappear by themselves and he was right but the skin is not "loose" I can't pull it to much backwards.

If a picture is needed I can look for something on the internet to give a better explaination...

So my questions are:
1. I haven't asked my doctor about masturbating but I do it anyway since it's not painful... Can I masturbate or is it a bad idea?
Maybe if I stop, the swollenness will go away?

2. I wanna start haveing sex with my girlfriend but Im afraid something will go wrong since my skin is "attached" to whatever I wrote

3. Any tips? Articles? Anything that can make me feel better about my situation?
