Well you are surely a pervert, but perversion needs to be examinated more closely to say, where your doubts come from. If its source is that you think, you are somehow guilty for what you are doing, you must look into yourself. For the feeling of guiltyness can grow whether on the ground of concepts of other people that you have adoptet as of yourself. And this will not work, as concepts of other people fit perfectly to their very own world but will always restrain you in your world, and by world I mean the reality in which you are currently living. Or it grows on your very own way of being, on the ground of your becoming that person who you are now. In this latter case, you have two possibilities. You can either evade those contents which give you that feeling, in other words to resist the urge, or you can give it one try after another. Then again, you can try to silence that voice during the future time but this might be a violation of your very own being, name it soul, mind, personality.
I know that I speak against those wo say, reality and ficition are ontologically two sorts of things. I think, we all live in a sort of fiction, which I have called "one's own world" further up this text. Noone lives in reality, as reality is something yet to be achieved by man and we all live in our own created world -which utterly rude for many and perverted for some.
Listen to youself.
