Well -- That's pretty much how I am, but I don't have a packer yet.
But if you're going to come out, then inform your teachers and friends... They shouldn't be offended and most teachers will support you if students become harsh. Luckily for me though, I have a friend who is also FTM and he's going to pack when I do so we'll both feel awkward but whole *nod nod*
If it's going to bother people then they'll have to suck it up if they really care for you, Do it for yourself~
