Hello Ubuntu1: You know... sometimes I think we'd all be a lot better off if having mental health related information on the internet were banned! (Perhaps I'll write a letter to President Trump.) I suspect more harm is done to people seeking mental health information over the internet than actually occurs as a result of whatever problem it is the person has to begin with.

I don't know about all of this paraphilia stuff, bdsm & bestiality. But I do believe lots of people have fetishes of one sort or another. Over the time I have been here on PC... (& this is my 2nd time here) I've read & replied to quite a few fetish-related posts, as well as the replies the posters have received. One conclusion I have drawn from this is that it can be extremely difficult to "break" or "cure" a fetish. The consensus of opinion seems to be that what is important is, first of all, not to feel guilty or anxious about having one. It's just one of those things that happens sometimes... no big deal. And second it is important to indulge one's fetish safely (& legally.)

Now having written that, I would also question whether what you describe even qualifies as a fetish. Personally, I can't envision any 25 year old heterosexual man who would not be turned on by the idea of a girl wearing a thong. I suppose there are some young men who would not. But I'd have to believe they are in the minority! Most men are simply driven by nature to seek sex. It's how the species is propagated. Plus, sexuality is everywhere in our culture. One can hardly go anywhere, see anything, hear anything, or do anything but what one is inundated with sexual suggestions.

So maybe, rather than having a fetish, you're simply a horny young guy who gets turned on by the thought of girls in thongs. There is absolutely NOTHING to be ashamed of, embarrassed about, anxious over, or anything else. Please try not to be so hard on yourself! You are most definitely not a freak! But if you find you simply cannot get past this on your own, then seek the services of a mental health therapist who has experience working with sexuality-related issues with whom you can explore the guilt & anxiety you are experiencing. It is this guilt & anxiety that is the troublesome thing here, not your attraction to girls wearing thongs.
