Zoophilia, also known as bestiality (although the latter has और negative connotations) is not a sexual orientation, it is a
philia.
Somewhere else on this site I explained the difference between a
philia and a sexuality, but I forget where it was... I'll keep an eye out for आप and link you.
But long story short, humans can have all sorts of philias, from the utterly benign, even sweet (such as agathophilia - प्यार of kindness), to the downright disturbing (coprophilia - प्यार of feces). While philia's often stimulate a प्यार so great it's sexual, they are not considered sexual orientations, like heterosexuality या homosexuality.
(

"A philia is quite narrowly defined, and generally revolves around a specific aspect of an object या individual (the aforementioned 'anthophilia' is an obsessive प्यार of flowers). It's not the same as simply liking the hair color of an individual, it's being exclusively attracted to something.
This, I would say, is the beginning and end of everything that philias have in common with sexual orientations. While still having some parameters (straights exclusively like the opposite sex, gays exclusively like the same sex), the variation within the definition is broad. And within that definition, a straight men might prefer brunette women, but he would never be attracted to a brunette man. This is one reason that there are both straight and gay age-philes."
That टिप्पणी दे was in discussion of a philia based on age (pedo-, hebe-, and ephebo-), but I feel the comparison still stands, as sexuality is often (unjustly, IMO) compared to pedophilia, which, like zoophilia, is a -philia, not sexuality.
Back to the सवाल at hand - are -philias a choice? All in all, I'd say not. I don't believe a pedophile, for instance, या a zoophile
chooses to be a pedophile/zoophile anymore than a gay man chooses to be gay. The difference between the two lies in victimization. With zoophiles, consent can never be given, and जानवर are not sentient, ergo any sexual act with an animal is considered rape. Similarly, a child cannot give consent as they are not considered to have adequate intellectual understanding of the act of sex, and so any sexual act with a minor is also considered rape. With sexualities, the acts occur between two consenting adults, generally in a reciprocal, equal-status, loving relationship. There is no such thing as a reciprocal, equal-status romantic relationship between a minor and an adult, because the adult holds all the power. There is no such thing as a reciprocal, equal-status romantic relationship between a person and an animal, because the animal is not sentient.
Hopefully, this will give आप something और solid with which to retort the अगला time this topic comes up.
