Strings?

Shelley
Has anyone experienced pain from their strings during sex? It feels almost as if they're shifting in such a way that's poking me inside, and I'm led to believe they're the cause because the area where he pain is located is exactly where my strings end. 
I will likely go to the doctor to have the strings cut shorter, but I'm also a little nervous to do so as then I likely won't be able to check them anymore. Thoughts?
