You know how we all find ourselves daydreaming or fantasizing about who we will end up with and what our family will be like? Well, I find it really exhausting! Before I accepted my bisexuality I forced myself to visualize marrying a man, having a family with a man, and forever being with a man. But now...well that has changed. I don't know how to visualize a future when I don't even know what gender my partner could turn out to be.
Forget the body, imagine the person, how they treat you, what you do together, where you live, a vacation you might take, etc.... Nothing wrong with a undefined appearance and body, that isn't what will make a relationship last anyway. All of out bodies change as we age.
