I feel guilty after masturbating...

I consider myself to be a woman of faith, though I admittedly do masturbate around my ovulating cycle every now and then. There'll be times when I'm highly aroused, so I'll watch porn and orgasm shortly after. The feeling when I over the edge is so pleasurable to me, but I can't help but feel 'impure' and 'sinful'. It doesn't help that I had a close friend who, in the past, made this comment of 'people being impure' themselves. Whether she'd been joking or not, it did strike a nerve, especially as she herself was a devout, sex-repulsed believer.

On one end, I find it so important to learn of my body, as I'm the one living in it my whole life, obviously.

But then, I'm constantly feeling lousy for giving in to 'sinful pleasure'. It's ridiculous how I still have such hang-ups when I'm in my early to mid-twenties; but then again, I grew up feeling as though my body was never mine, but God's.
