We have a glass front door, and we shower with the bathroom door open because it's an early-1900s house and we want to keep the humidity out.
I step out of the shower yesterday afternoon. As I am drying off, the 29yo neighbor walks up to our door from the side to bring us something. She sees me, takes a look, then steps to the side to ring the doorbell and not to stare.
She acted normal when my wife answered the door. I wish she knew that she could have stared.
I didn't mind that she saw me at all. I have seen parts of her over the years anyway!
Turned my wife on knowing that the young, hot neighbor saw me naked after a shower, too!
