Vaginal lining is at least three times as thick as anal lining. It is designed to receive a certain intimate foreign object and contract with muscular receptors which make said foreign object react, expand and give pleasure in return for the pleasure it receives, usually culminating in an ejaculation which is generally as pleasurable for the female organ as it is for the male organ. Feminists may disagree, but real women do not.
Anal muscular structure does none of these things as it is designed only for expelling poop from the lower intestine. That ain't a matter of opinion, it is a matter of physiological fact. Anal lining tears far more easily than vaginal lining, takes longer to heal and is far more susceptible as a source of and entry for disease.
Those who argue that homosexual activity is as pleasurable as heterosexual intercourse are even more stupid than those who would claim superior intimate experience with masturbation or a dildo.
Sorry if I offend anyone's sensitivities, but those are the facts. An anus has the ever present potential to spread disease, including fatal diseases, when it comes in penetrative contact with a penis. A vagina, on the other hand, can only contact and spread those diseases by allowing infected private parts to come into penetrative contact with it.
Further, said diseases, as bad as they may be, are generally only fatal if the infecting organ has been in or been infected by another organ which has penetrated an anus somewhere along the line.
IOW, nature has even worse consequences for homosexual activity than it has for wantonly promiscuous heterosexual activity. AIDS did not even exist before the normalization of homosexuality begin.
