Abdominal pain after masturbating?

Okay so yesterday I was feeling VERY FRISKY

I ended up mastrubating in the morning and orgasmed about 3 times and then repeated this at night and orgasmed about 4 times.

After all that, I started getting pain on the lower right corner of the stomach/abdominal area. When I press it, it also hurts!

Has this ever happened to anyone before?
