How to blow an uncircumcised dick

Ok I’ve been with my husband a while and I rarely give him head. He’s been horny lately but I just started my period 🤷🏻‍♀️

The thing is I always suck on top and never move the skin to touch the head because he says it’s too sensitive.

Is it normal?

I told him that normally guys have to move the foreskin themselves as I’ve heard but he’s from india and has never been told anything from doctors 🤔 he was taken to a doctor as a kid and the dr moved the skin and he said it hurt.

How can I do this?

He says it feels good if I touch it only a little bit but too much touching and it’s too sensitive.

Any help please, my husband is good at oral and I want to return the favour 🙈🙈🙈

Edit: thank for the replies. No he doesn’t want to get a surgery that’s why I ask how I could do it 🙄

Thanks Carolina, it helped a lot! It doesn’t hurt him as such I think it’s more uncomfortable for him but I will try that definitely!
