In my current project I have two characters who are experiencing varying degrees of sexual tension between one another. Now my current problem is I've never written this sort of thin into a story line and I'm unsure how to handle it. I want it organized in a way that the reader is well aware of the tension while the characters are completely oblivious (they're in denial...). I've been trying to brain storm how to do this but can't say I have much romance in my reading list that has dealt with ST before. Are there any suggested readings or advice anyone has for how to get this to work out?
