An unfortunate experience with ball play.

[TigerLover]

So this story is super embarrassing and crude but as i'm inexperienced with oral sex I need some help understanding what happened.

Last night I received oral sex from an older man. The guy really knew what he was doing(A+)
I like having my balls played with and I encouraged him to do so.

But towards the end he got a little over-zealous with the Ball play. It started hurting a little bit but still felt good overall and i was too far gone to correct him. So I just tolerated the pain, i guess. I'm not a masochist but i have a very high pain tolerance borne from a childhood of martial arts.

Big mistake! I woke up this morning and my balls were really aching. Pain tolerance be damned this fucking hurt, it was like bad back-pain but in my scrotum. It's faded now but they're still hurting.

Three questions.
A.How does this hurt so much more now than when it happened.
B.Should i go see a doctor or is this something i can safely ignore.

C. What are the odds that he did this by accident!
Do you think this guy was a closet sadist, doing this on purpose? Or am i being paranoid. How easy is it to do this by accident. He seemed to really know what he was doing otherwise.
