Oral isn’t my thing but I want to try and be more comfortable with it

I’ve only given my hubs oral a few times and normally I’m pretty drunk so I don’t really remember. Is there anything I can do to make myself more comfortable while I’m sober? Personally it just makes me gag and I’m scared I’m going to throw up. So then my anxiety gets going and I kind of panic haha. I know he likes it but I always back out last minute.

What can I do?

I also feel like I’m not that good at it so that makes me even more nervous to do it.
