What causes a desire 4 a specific sex fetish? how do i know if my sexual appetite & desires are normal & ok? some considered taboo according to society. (ex:rape fetishes, dom/sub acting turn me on)

Very common: These types of fetishes are very common and normal. As long as you and your partner are having fun and are safe, no need to worry. That means emotionally safe as well, if indulging these fetishes is causing you guilt or emotional turmoil, seek out a good mental health counselor to discuss this. Some people act out distressing scenes from their past in a safe way to learn to cope with trauma.

Earlier experiences: How our earlier experience influences our sexual fantasies is a complicated question. Things are considered problematic when one partner is hurting the other partner or the partner is not enjoying the sexual experience. Partners who care about each other can frequently get involved in sexual play that is more enjoyable to one than the other but hopefully there is mutual caring about each other .

Everyone's different: Everyone is different, which is to say, a person can be turned on by nearly anything. One definition of "perversion" might be that if you have 2 people who are so engaged, and 1 of them doesn't like it.

There are a wide: variety of sexual practices. Some would seem bizarre or abnormal, unless you happen to be a sex therapist, which might broaden your understanding in this area. The general consensus is that if a practice involves adults who are willing, not coerced, and is not painful, and can be terminated voluntarily without consequence, then the act is likely to be OK. A sex therapist would be helpful.
