Any tips for thicker dick?

So I’ve had my share of the different sizes and different experiences with each size but for some reason my most recent sexual partner has a thick penis and it’s not my first time encountering a thick one you know but for some reason I can’t work with it. Like usually I can still get in a good suck or two before I need to take a breather. But anyway this post is mainly asking if there’s any tips to lasting longer while giving head or in general. Because ya girl needs some 😂
