Do explicit rape scenes have a place in mainstream movies?

I wasn’t really sure how to word this question.

Explicit rape scenes have always made me uncomfortable, and I sometimes think that these scenes titillate would be rapists and may put ideas in people’s heads. I dare say, it turns some people on. I understand the artistic purpose, but is that purpose justifiable considering the possible effects and implications of showing such violence?

I’m not saying that rape scenes must be eliminated. I just get concerned with what media culture presents to the world.
