Yes, it's possible. You can pop a blood vessel in pretty much any part of your anatomy, so why should your dick head be any different? Aggressive masturbation, tight orifices, or attempting to insert your dick head in places it shouldn't be are all candidates for possible damage. Try something soft and cushy (like the avatar to the left) sometime....
OP, you're not going to get a better answer than this. I guess we can expect this thread to be closed now?
How do you do the shaking head little animation thing?
