Most of my life I have lived in a place that hetero relationships were considered 'the normal'. So I will always think that a bisexual person will prefer 'the normal'.

Surely you want your partner to be with you because they want to be, not because they lack options? 

The reality is that everyone has options. A gay man can leave you for another man. Or to go on a celibate vision quest. Or to move to another country. If a bi man is with you, it's because he wants to be there, same as a gay man.
