Dear Melody,
I think you're very brave in the first place to speak out about something very personal and embarrassing like this. I'm sorry you've had some responses that you found upsetting, but I hope you'll still keep reading. I don't want to judge you or condemn you, just share some thoughts.
On one hand, based on some of what you've posted, it sounds as if you're quite happy as you are with these feelings and behaviours that you describe, and if so, and if you're not actually harming anyone else, it's really nobody else's business anyway. On the other hand, though, the very fact that you find it really embarrassing to talk about, and have felt the need to start a thread asking if this is sinful, does suggest you feel deep down that it's not OK.
Regardless of what it is specifically that turns someone on, I suspect most people in the world wrestle at times with the temptation to fantasise and indulge sexual feelings. Probably all of us here have (I know I have). It doesn't help that we live in a world that makes out that sex is the be-all and end-all of pleasure and satisfaction and suggests that we all are, in the end, largely physical creatures who crave gratification in whatever way we can get it. And it is actually pretty easy to conclude (especially when feeling tempted oneself) that there's really no problem with that.
But what I find most helpful, when tempted to indulge in sexual fantasies, is to ask myself a few questions. Like these...
Is what I'm doing now teaching me how to be a more unselfish person? More genuinely, selflessly considerate and loving?
If I were in a real, intimate relationship with a real, living other person (which for me at least would have to mean marriage), would it really be anything like this self-centred fantasy in my head?
Is this bringing me any closer to God — teaching me more about Him, teaching me more about who He would have me to be, teaching me to follow Christ more closely? (Which, as a Christian, is my primary concern in life, even if I sometimes seem to forget it is.)
Has this fantasising ever actually made me feel satisfied — REALLY satisfied and fulfilled?
I can't remember a single time when the answer to all those questions has been anything but "no".
And that's what I'm getting at here, friend. It's not that sexual feelings (fat-related or otherwise) are "evil" and that God will strike you down if you indulge them. It's just that — outside the context of being just one part of a safe, loving, committed marital relationship — sexual feelings are largely a distraction from what
really satisfies and fulfils us, and from more important and unselfish things we could be focussing on.
I agree with what others have said, if this is troubling you, it'd be a good idea to seek counselling. But it also might help to work on deepening your own walk with God and getting to know Him better. Turn to Him — especially when these temptations come to you — and let Him tell you what He has for you to think about and feel and do. Just keep turning back to Him. It really is worth it.
