I need advice with him being uncircumcised

So I've been with this guy for a while now and we had sex and I was just wondering what am I supposed to do with the foreskin? Like not sex and condom wise, I know that. But like handjobs and blowjobs? Do I pull it back or just treat it like a circumcised penis? Sorry it's so tmi. (And yes I can talk to him about it but I'd rather just show him I know what I'm doing) or is pulling  the foreskin back or leavi g it a personal preference? I'm just so confused sos
