Should I downsize my ears?

I'm at a 16mm in my left ear and a 14mm in my right ear. I've just purchased an 18mm silicone tunnel so that I can stretch up again (I am to reach at least 20mm and then see what I want to do after that). However, I did skip a size (10mm straight to 14mm) and I stretched with a stretcher (some people refer to them as 'tapers', but I don't believe this is the correct term) and so it hurt pretty bad when doing it. It was foolish, I know and I am very careful when I stretch my ears, but I wanted to stretch them quickly. Anyway, they bled a lot and whatnot. I stretched my left ear up to 16mm and it's fine now. Occasional gunky stuff, but nothing serious. So, my question is should I downsize (10-14mm) and then stretch them again? Because I've noticed that some people's ears 'turn out' when they stretch too big, is this because they have stretched too quickly? Thanks in advance.
