I do not imply that the behaviors are compulsive. They clearly are rooted in desire. But desire itself does not make something normal. Biologically, it is undeniably unnatural.
Let me also say that of the examples you listed, only one is vying for equal status to natural human sexual function. That is homosexuality. That is my point. It might be a desire that some people have. As a free society, we might choose to tolerate it to a certain level. But it is not equal, normal, natural...etc...to heterosexual relations. It is not an example for children to follow. It is not something equal in function to heterosexual marriage and family. It is not just an alternative lifestyle and ideal for all young human individuals to consider aspiring to. It should be left on a tolerable lower status in our society.
