Hello, I'm a beginner at inflation. I've written a few inflation stories on my DA about inflation, but I want to actually do it. I used a foot pump for this with a DIY hose extension. When I try to inflate myself orally, my cheeks puff up and nothing else. When I try to do it anally (many times) I just get a disappointing fart sound. When I do it with water, I feel pressure in my butt then I just diarrhea it all out. What am I doing wrong?
