Does anyone have experiences to share involving themselves and a committed partner....where both were heterosexual? And one of the partner's become heavily involved with a bisexual partner (who allowed them opportunity to have relationships with that partner and another man/woman)?
For example, a husband and wife, where the wife was straight. Then the husband starts dating a bisexual woman. Because she's bi, he and she can share experiences with another woman....where the wife can't/isn't interested (otherwise, she wouldn't really be "straight" would she?)
Does it make it harder for straight couples to be poly, as they can't really be fully integrated with their respective partners, but each has to date on their own?
How do you get around that, if so?
