If you're used to having threesomes with her and her other lover, why would you call yourself mono? And why would she think that you are mono? It's not very monogamous to have threesomes, or sex with a partner's partner! I am also curious as to why you're seeking advice at a polyamory-focused site, since sex seems to be your motivation. Perhaps a swingers site is more suited to your situation and goals.
