It hurts

So I have a guy we r Fwb and seeing where things go but the thing is when he eats me out he’s good at it but his moustache keeps hurting me down there I wanna tell him but he’ll feel really bad and also he loves his moustache the only solution I can think of is not letting him go near there again but what if he think I hate the way he does if I don’t wanna hurt his feelings this all just really sucks what should I do
