I will let you know after I do it. My parents are the same way and I consider myself an pansexual as well. I know they won't take it well and I'm afraid they will take me out of the will.

There is a LBGTQ group here. You might mosey on over & pay them a visit.

Just a thought... GLAAD has hints and conversation starters. So does PFLAG. I wish you luck..this might be difficult.

I know this probably isn't super helpful, but you know your parents best. If it is a hard decision to make, perhaps make a pros and cons list of coming out to them. I never did anything like that- my coming out was very spur of the moment and unplanned. The best approach, is the best way you can think of. None of us online know your parents like you do.
