LGBT Completely Desensitized and Confused?!?

Ive recently come to terms with the fact that I might be bi-curious (im a guy btw) but, after coming to this realization, ive become completely desensitized. Ive always been attracted to girls for as long as I can remember, its just been who I am, ive gone on a few dates and loved every minute of it, but for the past few years ive noticed physical reactions when I come into contact with other guys. I know that coming into contact and being by guys doesn't make me biual or gay, but ive also been having these (and very enticing) thoughts of being with other men. All this has been happening over the past few years but its only been within the past week and a half that ive come to realize im bi-curious. I don't have a lot of male friends, everyone moved away to go on to colleges all over the country while im stuck in community college (which sucks btw) so I really don't have any real way of confirming whether or not these feelings are real. But that's somewhat beside the point (enough of my own pity party "boo hoo all my friends left me" crap), in the past 3-4 days (ever since I started second guessing myself) Ive completely desensitized myself of all emotions pertaining to affection in both girls AND guys. This new guy started working at the grocery store where I work and all day long I really couldn't get my mind off him, but it wasn't physical attraction, (even if he was kinda cute i guess) or possibly even emotional attraction, (like I said, desensitized to all emotions) it was just so confusing. For most of the day almost all the thought in my head were about him, I just wanted to touch him by "accident" just to see if I reacted (I didn't react btw but Halle berry could have walked into the store completely naked and I wouldn't have even flinched) and Im just so confused cause I honestly CAN'T feel anything right now. Its like my mind was saying "your totally into this guy" but where my heart was, all I could feel was this great big hollowness, and I didn't feel any stirring of emotion all day long from anything. During my lunch break I tried thinking about this extremely hot girl I say a few days ago (on a normal day it would have been the best daydream ever) but my body didn't so much as twitch in any way, shape, or form. As if I wasn't confused enough I don't know how to "re-sensitize" myself, If I did then I wouldn't be asking this question. It feels like I want to be with this guy (even though this is the first time ive ever worked with him or seen him for that matter) but at the moment my heart feels like this giant unfeeling, unmoving, void of emotion and I don't know how I really feel about this guy. And Im not really sure im even attracted to him, Ive never had a crush on a guy before so I don't exactly know how I would feel but even so, he was constantly on my mind nonstop for my entire shift at work. Is there anybody who can help me re-sensitize myself to emotions or at least help me with this situation?!?!
