Did I get a thrill from my first time being flirted with by a straight girl? In the words of the abridged version of Seto Kaiba, "Oh God yes (+1000 dead puppies)".
She was actually a coworker (a really, really gorgeous coworker), and it was our first week of training for our job. We'd gone to the office to fill out some paperwork, and I got there just as she was heading out. As we walked by each other, I asked her where I was supposed to go. She looked up at me (God bless those itty-bitty 5'2" girls with just enough curve in just the right places) with enormous dark eyes. "Right over there, Mr. ______. It's just a couple of things. I'll see you later." And then she proceeded to run a hand down my (bound) chest from shoulder to below the ribs.
Oh, testosterone, the gifts you bestow upon us - not the least of them tiny Greek girls with luscious long hair, eyes, and...well. Quite a few other parts which definitely fit the "luscious" category.
