A few things that come to mind with humor.

• You can (or should not) go into a bar without a companion
• Females include you in their secret chit-chats (that's why I transitioned, just for that)
• Make sure to read the restroom sign (ooooops I made that mistake already, got some looks)
• Female products have a "Woman Tax"
• Pany liners uug
• You start noticing things like oh, my legs look crappy, exfoliating time
• Stay way from Victoria's Secret's, you can pass by one and not buy a new bra, panties, lotions etc.
• Panties rubbing against private parts may cause unexpected O's that will not stop
• It's more difficult to shave underarms with real breast.
• You will put a thong on backwards at least once
• Shoe purchases increase, you need a room for all your shoes so you kick your son out to do this (only kidding, gave him two months)
• It may not seem like it but dilation is crap at first but gets better and less frequent. The real thing is a better way to dilate 
• Larger than a 34B cup bras come in less colors (damit), stores seem to cater to 34B more than 36C.
• It will become more and more apparent "It's a man's world"
• Dating becomes (at least for me) easier but also you get to see things through a mirror.
• You now love to listen to Katy Perry
• Clothing and shoes, at home becomes optional
• You enjoy Tofu and fruit cake
• Toilet seats seem less cold (yeah right)
• Toilet paper, can't be without it now. I keep a roll in my car and wipes in my handbag
• Your journey is finished, far from it.
• The ride is more enjoyable through life.
• Miss something from your former life (penis envy haha), there are strap ons for you.

I am sure there are many more things I have not thought about.
