that photo alone is enough to make men grow tits
Also, I'm not as anti-poly as some in this thread, but if your primary partner has quit sleeping with you and is sleeping with other people, that seems to me like the relationship has a serious problem that should be addressed.
I mean, it's one thing for someone to have a variable sex drive due to the usual reasons (trauma/medication/menopause/illness/etc), and that's a real challenge many couples wrestle with, but if the person you're dating isn't interested in sex with you BUT is still having sex with others, y'all need to sort some shit out.
