To Glenda, I'm sorry but that's the most incredulous argument anyone can make. First off, if you knew anything, yes people and animals excrete waste from the rear, but 90% of the time its pretty much empty so its just as clean as vaginal sex. Secondly, contrary to what you may believe, the penis also fits quite well into the anus, infact better as men who are larger can be accomodated better into the anus, as the muscles there tend to strech more than the vagina, and the vagina ends at a point, the anus and rectum go quite a bit farther. And lastly, the "Adam and Steve" arguement. Oh the ever faithful psycho christians favorite argument. Let me point out first that I'm not anti-religion. However if you want to be historically accurate, and i'm sure you would, homosexual behavior in HUMANS existed long before and long after biblical scripture was written. So for you to assume that God made people for exclusive heterosexual sex is blatantly wrong and historically innaccurate. Also, the fact that you even brought up adam and eve reveals to me that you obviously put no creedance in science so i dont know why i'm bothering to argue, but this article makes a vaild point. If it exists in nature, then its natural, and bible thumpers and bigots such as yourself should realize this. Yes this article has an agenda, but its only to prove that homosexuals, such as myself, aren't godless sodomites who are doing this because we "want to". Our very nature has more to do with it than you may want to admit, but here we are.
