bleeding

I got a message from a gentleman with a healed Prince Albert piercing. He was alarmed at seeing some blood after masturbating:

Hello, this is a bit scary. I got a PA a while back. About 5 years back to be exact. All went well, I've since managed to stretch to an 8G. Two days ago, I switched to a captive bead ring. This took a little work, as the bead did not want to pop into the jewelry.

Weird thing is, I um. Well I pleasured myself today, and to my horror was a bunch of blood mixed with semen.

1) It doesn't look swollen, infected, etc
2) There was absolutely no pain before during or after this happened, nor while urinating, rinsing, anything.
3) It sometimes feels a tiny bit sensitive, but nothing I haven't felt before when adjusting to new jewelry.

It definitely freaked me out as the only other time it ever bled was 5 years ago when I first got the piercing.

My reply:

I received this message via email:

Hi Elayne,
I am having a situation with a piercing I did. Sunday afternoon I did an industrial piercing on a girl named Alex. I'm still an apprentice but this was the 10th industrial piercing I've done and I have never had a problem with any of them up until now.

Alex called me this afternoon, 2 days later, complaining that her piercing is bleeding and she can't get it to stop. It hardly bled when I pierced it, and up until last night when the bleeding started, she said that it was healing just fine. It wasn't sore, red, no signs of infection, and didn't hurt at all. First thing I did was try to figure out how the bleeding started. She said she took 500mg of ibuprofen and the bleeding started shortly after that. I understand that a side effect of ibuprofen is blood thinning but unless she was already bleeding I didn't think the ibuprofen would cause her to start. I just thought it would make it a bit harder to get the bleeding to stop if she did happen to start bleeding. Am I wrong about this?

She also said she thinks she accidentally rolled over onto it in her sleep which would make more sense except that it started bleeding before she went to bed. Is it possible she is just not telling me that she bumped it or something, or is it normal for industrial piercings to randomly start bleeding days later?
