Wanting oral but he’s not into it

Not sure if this is where I should post this but

My bf told me back like in the beginning of the relationship he’s never been into giving oral and is aware he’s not good at it. He has given me oral pleasure maybe like 5 or 6 times out of the 2 year relationship ( I love how it feels even though I didn’t orgasm every single time)

I honestly want him to do it more often but I feel embarrassed or shy to ask just because I know how he feels about it and it’s like I don’t necessarily want him to do it cause then I just feel like I won’t enjoy it knowing he’s not enjoying himself ( does that make sense?)

But then I think of when I give him blowjobs I don’t necessarily love it but I still do it for him since he enjoys it very much.

So does it seem fine to ask for oral pleasure..
