I'm a new member of the group, and I notice one of the rules is 'Please submit to correct gallery'. Very reasonable, most groups have a similar rule. Transgender - a change of sex or gender (mtf or ftm); Crossdressing - wearing the clothes of the opposite gender. It seems simple enough.
But modern technological developments (in our virtual worlds, not in Real Life) seem to have blurred the distinction somewhat. I use the concept of 'bodysuits' quite a bit in my captions. Bodysuits can range from something you wear for 24 hours to have a bit of fun as a member of the opposite sex (so crossdressing really) to something that has bonded with you, become part of you, and changed your outward sex permanently - clearly transgender. There can be every gradation in between. So the distinction seems to be - how permanent is it?
Now I'm doing a series of captions (I haven't uploaded any to this group yet) called The Girls of St Gwen's. It's set in an all-girls boarding school where the students are all boys (!) The bodysuits they wear can be kept on for 2-3 months without ill effect before removal and a medical check up is necessary. The 'girls' attend this school for 6 years. Afterwards they can go back to being male if they want to, but only about 30% do - the rest choose to stay female permanently. This seems to fall halfway between Transgender and Crossdressing.
So where is the cut off point between these two categories? I suppose I could just ask an admin, but I thought it might be interesting to see what the members think. What do you think the 'cut off point' should be?
