Giving Uncut A Bj

Is there any special way to give an uncut guy a bj? I’m just not sure to do with all the foreskin. Do I leave it over the head? Pull it back? Use it while I’m giving a bj sorta like a hand job?

I’ve yet to see an uncut dick but I want to have some knowledge before i have one in my hand. I’m bound to run into one in college at some point.

All my friends have only ever had circumcised guys. I totally asked my mom if she’s seen an uncircumcised guy and she hasn’t either. She’s only dated two guys in her life. A boyfriend in high school and my dad both are circumcised she told me.
