Should I date my stepbrother?

[The Commander]

I think the point about having to see him on a regular basis even if things kind of turned sour is a pretty valid point. 

The whole scenario brings back memories from my cultural anthropology class when we talked about different concepts of incest.  I specifically remember when we talked about how in some cultures you are not considered related to half-siblings if they are half siblings via your father.  It made me think about my own half-sisters and wonder "Would I hit it?"

I decided to quit thinking along those lines before I got myself into trouble. I was ruled far too much by my libido at that time...
