i'm 22 now, and i live in a rural part of ireland, so i'm not exactly as sexually active as i'd like to be, as a result, i masturbate. alot.
i was about 16 when this happened, but didn't get the concrete evidence until recently.

i was shaking hands with beef, for the second time on the same erection, and nothing was really happening. i was getting frustrated.
so i kicked into fifth gear, stiffening up and getting my shoulder in on it too.
after about five minutes of this furious futility, this really deep pain started in my right boob. like so deep i thought it was an organ or something. the pain got worse and wouldn't let up, so i did what any normal teen would have.
i switched hands.
i eventually finished up and tried to ignore the pain.
after about three days the pain went.

about six months later i was in the shower, and i noticed a bump in my chest. i immediately panicked, mentally writing my will, trying to figure out something witty for my gravestone etc. 
after seeing the doctor i was referred for an xray, as the bump was very hard, and he was concerned.
now because i'm on a medical card, alot of my treatment is free, but i have to wait ages.

a year later i get the xray, and i'm told to wait for a letter to come back for the results.

another year passes, and i get the letter. i go to my doctor, and he gives me the all clear! 
he tells me it was a fracture that had healed awkwardly.
now i'm not a sporty guy, so i'm baffled as to how i fractured my rib of all things!


then i think back to that lonely night in my room, and it all clicks.

i fractured my rib wanking.
nobody knows the truth behind all of this but us.

shhh.
