Evidence indicates that "monogamy" does not have the same meaning in gay relationships, with both "life partners" sharing multiple partners outside the relationship, and with the central relationship averaging something like 4 years.

Marriage has never guaranteed monogamy.

"Marriage has never guaranteed monogamy."

Exactly.
If a person is determined to screw around, they will do so regardless of marital status or how anyone will be hurt by it.
Such people, hetero or otherwise, do not care about consequences, they only care about their feelings and desires in the immediate moment.
Marital status only adds a layer of complication for them, something or someone to have to lie about or to.
Another thread of deciet in their unending web of lies.
'trager has it right, as do others stating the same thing.
