This is like asking someone if they figured out how to blow their nose on their own, or, if they were shown. Personally, I don't like tissues, or cheifs. I like to use a wash rag, nice and sturdy to clear the sinuses out during a run or when it's cold outside. That or, I just pick it.
Some people have soft noses that are easy to discharge, and can use tissues.
Some people just snort it back and never blow their nose.
See?

Once you get the hang of it, then as long as it works then why not.
I never double layer as far as tucking, I don't mind the bulge, and I wear mostly skirts anyways so it's not a big deal to me. I suppose there's methods to sitting and walking that help a whole lot, I couldn't refer to anything specific though. Once again, just something that's picked up.
I wear small regularly, so I usually just buy extra small panties. I've been trying to get into thongs more, but I always feel that the, "long thing," rides up a lot in them.
