hi friend, i totally agree with your opinion.but it is foolosh to compare humans with animals.i'm not saying this,as we humans are thinking that we are superior than animals because of having extra sense.ie.sixth sense. but we social animals because behave very worst than the normal animals.eg.i've not heard or seen any animal being called as lesbian, or homosexual.we should be ashamed of it and try to maintain som value in relationships.the complete functionality of this world is running due to attraction between two different sex.
