Crossing the Line?

I like to browse through other people's artwork and aspire to become an artist myself. I do see pictures of couples and love, but how far is too far? I'll admit seeing some that were not appropriate(and quickly did a mental rinse :eek: ) but sometimes the line is blurred. What is crossing the line?

Jesus,our Lords peace be whit You.
You need to trust Your faith on this one,too far is when You feel bad.

The line is different for everyone, more or less. But keep in mind that the idea is not to see how close we can get to the line, but to draw closer to God and holiness.
As St Paul said, all things are lawful, but not all things are profitable for us.
