Condoms and Penis Size Questions (Not Related...)

Hi there, I have two questions... Question 1: On an UNCIRCUMCISED Penis, do I have to unroll the ENTIRE condom or just enough to get to the base? I'm asking because I'm 5.5 inches, and I have leftover material within the little rim on the condom. Do I have to roll the foreskin back over the head, which would allow me to continue rolling the rest of the condom down, and then pull the foreskin back once the entire condom is unrolled? (I hope this makes sense!...) Question 2: In the UK, what is the average Penis size in length and girth?

Q1 Just roll the condom down to the base of your penis so it’s all covered. It’s easier and more comfortable if you are already fully erect when you do this.

Don’t worry about the extra material. Regarding the size of the condom its width/girth that matters not length.

Q2 I dont have the exact figure but you sound average length
