Where's the line?

The other day I was discussing with some friends where the line is between what's appropriate and what's not. We were talking about a video we had seen and I felt included inappropriate sexual innuendos. I let people know that it offended me a lot, because of how sacred I feel that physical intimacy is. Everyone else felt like it was a funny reference and wasn't offended by it. It's interesting how everyone has a different line that they agree with.
