So let me get this straight. He and She have been together for 9 years. You and her have been together for 2 years. But he has sex w/ her, of course because they have been together for 9 years.

You and him have sex even though you are not really that into it. He prefers you sexually over her. But because he has been w/ her longer and doesn't want to hurt her feelings, he is only affectionate towards you while she is not around.

She on the other hand is not concerned who he is affectionate and sexual with as long as it it is one of the two of you. Both you ladies are bi, so it stands to reason that the fact that you and him share a sex, and she and him share a sex life, since you both do it is of little concern to her.

Do I have this correct. I don't want to jump to any conclusions.
