So,.... what's all that mean? Do you satisfy your lesbian urges outside the marriage? If so, have you and your husband discussed this and he given you his blessing? And is he free to do the same?
I don't think the world needs labels, per se. But I do think we need honest, open communication about what to expect in the way of monomogy and desire within our relationships. And I don't think that it's your spouse's obligation to assist you through "finding yourself" or "exploring your sexuality" when that's code for "cheating on you". The vows of marriage include "forsaking all others". Your partner doesn't owe you their loyalty in assisting you with breaking that vow.
