Can anyone explain vaping to me?

I smoked for a couple of months once but gave it up because I'm hopeless at lighting cigarettes without them snuffing out. I bought a vape once and couldn't get it to work. So I went to another supermarket and asked the young person serving me if they knew how to set it up and if I bought it, could they do it. And they did. I opened it and they showed me how to use it. But I couldn't figure out how many times you're supposed to vape on it as compared to a cigarette. With a cigarette it burns out but the vape keeps going on, so how do I know the right amount to vape?

I've never seen the fascination with smoking/vaping. I tried smoking once as a kid and I hated the smell, taste and the way it made me feel.

What helped me was switching to a simple button‑free disposable, so I didn’t have to fuss with lighting or fiddly parts. I also tried a few brands in bulk from usa vape wholesale, since getting a mix let me figure out which ones were easiest to hold and draw from. Even small tweaks like choosing a lighter device or one with a tighter draw made the whole thing less stressful for me.
