We would like you to classify each of the following sets of argument pairs (discussing Gay Marriage)  into either SIMILAR or NOT SIMILAR. A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET. A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.

Sent1: Also, promiscuity and unsafe sex are not relevent to a discussion on gay marriage, as those who are promiscuous and unsafe don't want to marry.
 Sent2: A benefit to heterosexual society of gay marriage is the fact that the commitment of a marriage means the participants are discouraged from promiscous sex.
