Just wait and you will say that "marriage forms" (where party-A and Party-B signs)have a clause:<quoted text>
How would any society or government make homosexuality (compulsory) a person can't control what their sexual orientation is? You act as is someone can dictate your sexual orientation to you, if that's the case you might be already gay, or a bisexual in the least.
Have Party-A and Party-B, involved in some "same sex" "foul play"? If yes, sign one, if No, come back after one year!!
It is so simple, why you could not get it!!
