When a single kiss calls your sexuality into question, there's only one sure path to a reliable answer: further research.PatrickI like to think I know myself outside and in. As a developmental psychologist, I've spent years exploring the true foundations of my identity. So, when losing a bet means kissing my best friend, Logan, I already know I'm going to hate every second of it. All the relevant questions regarding my sexuality were asked and answered years ago. The results were conclusive: despite the odd same-sex attraction, I dislike being touched by men.That is, it seems, until Logan is the man doing the touching. The intense desire aroused by his kiss contradicts all my expectations and I have no idea how to integrate the new information. Thankfully, I know exactly how to uncover the truth about myself-once and for all.LoganI've put a lot of effort into keeping Patrick out of my fantasies and in the friend-zone. Our recent lip-lock may have unleashed my feelings for him temporarily, but I'll get them back on their platonic track in no time. Falling for a friend, especially a sexually ambivalent friend, is a one-way ticket to heartache.But, when the unforeseen impact of our kiss inspires Patrick to conduct an experiment into the extent of his bisexuality, I can't resist volunteering to help. If any man is going to join Patrick on his journey of self-discovery, it's sure as hell going to be me.
