Not very

Watching your life flash before your eyes in the span of a second, you notice that despite being radically different in many places, it's largely the same over all.

Putting your wallet back in your pocket, you operate on auto pilot as the line moves up and grab your regular lunch before walking over to your normal seat.

Casually making small talk with your small circle of friends as you think, you note that in this reality, many of them are changed to much of the same degree as you being almost entirely female aside from the dick.

Letting the normal sounds of the conversation flow over you, you see that they still share the same likes as before aside from exchanging information about stuff like clothes and makeup before your interrupted.

"Hey John, you there man?"

Blinking as you look up, you see that it's Mike, one of your best friends since middle school. He is the one that convinced you to go almost all the way in the transformation, whereas before you mostly wore maybe a pair of heeled sandals, or a skirt.

"Ya, just thinking." You reply.

"What about?" He asks.
