So what happened next? Did you immediately leave, or stop and stare for a minute? And how did you feel seeing him jacking off? Did you apologize for accidentally walking in on him?
I recently had SMS cyber with a guy (my first cyber!) and when he was describing how hot he was for me and what I made him do by writing to him I felt extatic. Even better when he got my pics and the pestering got "worse". I'm secure about my personality but being sexy... it's not a concept that comes easily to me. I was always praised how smart I am. Never how sexy, pretty etc. I never walked it on anyone. But I'd love to. Unfortunately my only sibling is a bigoted nun in sexy clothes.
