Same-sex monogamy is honorable, so a same-sex civil monogamy license should be provided. However, same sex partners cannot procreate independently: they must contract for surrogacy, either directly or through the surrogacy industry. Surrogacy introduces extra biological and psychological risks to children. Also, same-sex partners cannot provide children integral heterosexual role models and providers. One or two men must learn how to dress a girl in diverse circumstances, whereas a mother would already know. One or two women must teach a boy how to catch a grounder. Moreover, children of a gay couple cannot provide the psychological input that is available through an integral, heterosexual couple. Two women have to teach manhood by exhortation, not example. For civic reasons, a same-sex partnership is not equal to an heterosexual couple.
Since some heterosexual couples may procreate before maturity for parenting, and since same-sex partners cannot procreate without the risks attendant with surrogacy, support of children would be enhanced by procreation licensing. For example, only couples with civic monogamy license of some duration, say three years, could apply for a procreation license. Only women older than 23 and men older than 25, when their respective bodies have completed their respective brains, could obtain a procreation license.
Being the most aware species, humans can agree on intimacy for reasons the couple or partnership decides. It can be purely for sexual gratification, whether mutual or not, or it can be for bonding. Group bonding--fidelity--beyond group sex seems farfetched, but human imagination constructs unlimited variations. However, the noblest requisite for intimacy is mutual commitment to monogamy. If the purpose is monogamy and there is potential for pregnancy, care must be taken: either there must be provisions to prevent pregnancy or the couple must be committed to sharing their love and mutual commitment with any offspring. If the couple agrees to extend their relationship to offspring, the resulting family is integral: has shared blood lines that extend the genealogical continuities of two family lines and the millions of years of evolutionary developments represented by them. Any children who benefit from this monogamy have the potential to extend those blood lines along a new branch, and the resulting, basic unit continues a civic and genetic heritage. If there are elements within that heritage known to be bad, the memes can be terminated with awareness, disclosure, and alternative commitments. For example, awareness of a grandfather's bad temper can be the focus of training not to mimic the behavior. These last few considerations are true for heterosexual monogamy only, since shared blood lines are terminated by same-sex monogamy. In fact, with surrogacy, the parent has no way of anticipating the genealogical issues the child received. Because heterosexual sex can cause pregnancy, perhaps leading to a newborn, and because neglected newborns, children, and adults become wards of the state, heterosexual sex is a civic issue and therefore a subject of government. Also, because procreation is necessary to maintain a people, heterosexual sex is a government interest, which this nation financially supports. Same-sex practices should not dilute the financial support for children, and any future tax savings regarding this issue, for example, ending the marriage benefit for childless couples, should be dedicated to child support services.
