Persons who are considered to be bisexual are attracted to members of both sexes, but this doesn’t mean that they feel the need to be with a man and a woman at the same time. Just like straight or gay people, the vast majority of bisexual men and women will want a monogamous relationship. When it comes to marriage, a bisexual may end up with a partner of either gender. If a woman marries a man it does not mean that she is straight, and by the same token, by marrying a woman, will not make her gay. The person that they marry will be the one they are in love with as a person, and may or may not have anything to do with the person’s gender
Understand that many bisexual people will not prefer one gender over another. Many, even those who eventually marry, may shift between sexes depending their feelings. When entering into a serious dating relationship with a bisexual person, be prepared to accept their attraction to another of a sexual difference – the same way straight or gay people are attracted to members of their preferred sex. Remember that if this person is dating you in the first place, it is because they are attracted to you as an individual.
Respect your date’s bisexuality as part of his or her identity. Understand that they could also be mostly one or the other, which in fact makes them bisexual. Most bisexual people consider themselves to always be bisexual, no matter who they are dating at the time. It is important not to suggest that they are heterosexual if they are in a relationship with a person of the opposite sex, nor that they are homosexual if they are in a same-sex relationship. As such, do not question when they meet someone of the opposite or the same sex, and are attracted to them; but accept them as they are if you wish to retain your relationship with them.
Enter into a serious relationship with a bisexual just as you would with any other person of your preferred gender. Understand that if they are attracted to a member of different or the same sex as yours, that they are not cheating on you; just as straight or gay people will be attracted to other members of their preferred sex. Remember that your partner is attracted to you as an individual, and by understanding that they wish to remain with you, it will make your relationship stronger. Remember that in a serious relationship, your partner should not only be your lover, they should also be your best and most trusted friend. If you feel you cannot accept this, then do not enter into the relationship – but do remember: it’s no different than how, for example, an exclusively heterosexual person will always be attracted to the opposite sex, but they are in a relationship with you.
Maintain a healthy relationship with your bisexual date, as you would with any other date that you enjoy being with, or even love. Be honest with them, be open with them, and share thoughts and feelings. Forgive one another and tell the unarguable truth when it comes to disagreements, learn to appreciate your partner rather than show unhealthy criticism. Help each other when needed, and communicate openly about most any thing as you would, with a person of your same sexuality.
Give them space. You may want to constantly ask them what gender they prefer at the moment, how they feel, etc. – don’t.
