The simple truth is that married husband and wife couples have three basic forms of sexual contact. These are vaginal, oral, and anal. And of these three, only one has been demonstrated to produce a baby. And of the three only vaginal has been proven to be healthy and without serious complications under normal circumstances. Both anal and oral sex can bring about serious sanitary health risks to those involved.
With homosexuality, there is only two possible forms. They include anal and oral. No baby can be produced and both have serious sanitation/health risks involved.
You need to do more research if you think that's the only way to have sex (and the only way to procreate).
