It would be hypocritical of me if I answered in the negative. If I expect someone to date me, then they also have the right to deserve the same.
Also, I am of the firm belief that one needs to be faithful in a relationship... So, if you're dating a man and you like a girl, you should never pursue her unless your partner is in confidence and is totally comfortable with it.
Even then, I would never date a person who's not faithful. A mistake committed once can be forgiven, but if he/she has a history of being unfaithful, then.....

So, the net result of my rant is...Yes, I'll happily date a bisexual man/woman if he/she is of my interest.
