Science show proof as a fact, not opinion that sperm is designed to penetrate. It will be drawn to go straight straight to the hard shelled egg in a woman's womb and start penetrating it to form a zygote (baby). The vagina wall is very strong and it can withstand millions of sperm penetrating at it and NOT ONE sperm will be able to burrow through the vagina wall. The anus wall is not the same. Its wall is very tender, soft and fraige. When sperms enter the anus area, it has absolutely NO PROBLEM burrowing through the anus wall. Once it is out, its next goal is to drive straight for the immune system and start attacking it. The immune system begins to weaken. It makes the human become more sick and die faster. This explains now why God did not promote homosexuality.

This is often found in homosexuals and men who has had a vasectonomy--- their immune system are not as strong.
