What, if any label you may use can have as many differences within any one group and possibly less between others as You ARE You.
Some who see themselves as Sissies do dress in a more LG way, less puffed out shall we say and while so are very much centered on child-like play than grown up sex, shock horror do get along with LG's and we all need to "read the room" presenting and acting accordingly.
That does include LGs who go into Sissy posts like in this bit of the forum and basically pout, stick their tongues out fingers on the tip and blow raspberries at sissies, derailing their threads.
I love being LG but that's bratish behaviour and not ladylike.
