You wake up in pain, grouchy and groggy and begging for morphine. Then they give it to you and your memory sort of blacks out. A year and 7 months and 2 follow-up surgeries later you're still not feeling completely back to normal.

There's residual soreness and numbness even this far out. (Funny, I chose my surgeon partly for his one-stage procedure, but so far it's taken 3 surgeries to get it right.)
One week after SRS you realize you never imagined it would feel this right to be free of those dangly bits. At 20 days your first "big O" simply blows your mind.
Riding in the wheelchair in the airport on the way home you feel every bump and vibration and it's uncomfortable. You feel like a delicate flower, or a banana that's been peeled.
Then after a year or so when the swelling has gone down you can look at your equipment in the mirror and feel really good about having something that you've always wanted and always felt should be there.
