It all depends, often asking is one thing, but if somebody sets their preferences to what they want in sex or a relationship, you must respect them on it. I tire of people rejecting me for just be bisexual, but things like I do not get in the way and move on. As long as they base it on the rejection of preference and not on my own faults, will I dwell on it a bit at all.
Blaming others for their own wants and desires is a self-issue. Also, I would suggest that you may wish to state what you want and put it out there to better get people to notice you.
