Awkward situation...saw guy I know masturbating on website?

[Wasting time for 6 years]

I was on omegle trolling and what not, and one of the people I came across was a dude that I know is in my chorus (I'm in college). He's really ugly and weird and has probably never gotten laid, so I guess it explains his desperation. So, I did capture some of it. Should i upload it and show it around? (I know some of his friends..the guy's face is visible, I blocked out myself, but I was fully clothed and looking normal). This is too good for me to do nothing with it. I think he facebook messaged me, but I haven't read his message yet.
a) I was trolling. I never get naked on sites like that. Amanda Todd anyone?
b) No photos of me naked anywhere. No one has seen my naked post puberty.
c) you shouldn't be masturbating on camera for a bunch of strangers. It's quite different than making out with your same sex boyfriend in the privacy of your dorm room.
