Okay, Here's the Deal

I was having a conversation with one of my housemates. We think ourselves decent guys. We live in one of the most populated metropolitan areas in the world. We have good paying jobs in the tech sector, I may even say great paying jobs. Now, this part may be a stretch, but I think we’re both pretty good looking. (Work with me here.) Now. . . My question is this:

Why aren’t they lining up?
