Modern psychiatry doesn't consider paraphilias (fetishes) to be mental illness unless they cause excessive guilt or anxiety, social difficulties or sexual dysfunction, or harm to self or others. When they do, the treatment focus is on reducing guilt and anxiety, solutions to the social difficulties or sexual dysfunction, and finding safe ways to express the fetish and resisting harmful behavior–not trying to change or eliminate the fetish, which doesn't work. There are rare reports of people changing orientation or sexual preferences after strokes or similar brain trauma, but obviously getting rid of a fetish isn't worth inflicting something like that! These reports also suggest that fetishes and sexuality are indeed innate, part of brain structure, and formed during early brain development. Since any fetishes you may have are part of your brain–a feature, not a bug–you can't give yourself brain damage by indulging a fetish, unless you engage in risky activities (such as choking, blows to the face, certain types of drug use, or coprophagia (which can lead to infections that in rare cases can spread to the brain)). Unless you are masturbating so much that it interferes with everyday life or relationships, or doing risky activities to fulfill your fetish, there is no need to be worried about having one, and "quitting" the fetish, except for a short period (1-2 months) to defamiliarize yourself with erotic materials so they become more effective, is probably unnecessary. Most cases of excessive masturbation or hypersexuality/compulsive sexual behavior aren't actually "sex addiction," but symptoms of other problems such as anxiety, OCD, PTSD (especially from sexual trauma), mania, depression, or even neurological or hormonal problems such as persistent sexual arousal disorder (PSAS, sometimes also PGAD, persistent genital arousal disorder). In some women, premenstrual dysphoric disorder (PMDD) can manifest as mania, hypomania, and/or unwanted arousal. Pornography use itself does not cause "sex addiction," and abstaining from fetishes or masturbation/sexual activity may make mental health worse. (For males, it is also better for prostate health to ejaculate at least 2-3 times per week. Besides being dubious reasoning and bad science at best, "nofap" can literally give you prostate cancer.) If you're experiencing any kind of compulsive sexuality, investigate other physical and mental health problems before deciding that sexuality itself is the problem.>>24395
OP, it's fine to take a break from scat if you want–ultimately, it's your decision!–but it probably doesn't need to be as long as a year, and trying to quit it permanently will probably just make you miserable. While it's normal in our culture to feel shame about fetishes, particularly ones like scat, fetishes are not bad things, and shame is usually a thing to try to get rid of over time, while still retaining the caution appropriate to staying safe in a sexphobic/fetish-phobic society. If you want to diversify your tastes in porn, think about why scat appeals to you–for example, loss of control, messiness, sadism/masochism, and humiliation are common themes–and see if any of those aspects also show up in other types of porn. For example, if you're into scat where someone loses control and messes themself, you might find forced orgasm porn appealing. Meanwhile, if you're more turned on by the scat being messy and getting everywhere, you might also be turned on by cum marking or bukkake. In general, scat fetishists tend to prefer buttocks to be emphasized in other types of pornography. Really, though, best of luck with coming to terms with your kinks, in whatever way works for you!
(Note that what is "kinky" is highly culturally contextual, and while most people have some kind of sexual fixation, some of these are normalized by society and aren't culturally considered kinky. For example, it is common in the West for men to be fixated on breasts to the point that it would be considered a type of partialism fetish if it were another body part, such as feet, in rare cases even to the point of breasts being a trigger for premature ejaculation. However, since in our culture breasts are considered very sexual, such men are considered fairly normal for the most part. Meanwhile, other cultures, especially in tropical areas where wearing less clothing is common, consider the idea of finding breasts particularly arousing compared to other non-genital parts of the body is considered abnormal or ridiculous.)
