*Real events, fake names.*
So, I have been in a no-strings-attached, Friends with Benefits arrangement with a fellow student at my university, with whom I share several classes, since Spring semester. Her name is Rachael and she and I started out with a flirty chat when she sat next to me in a lecture. This led to me asking for and receiving her number, which led to drinks, which led to other extracurricular activities. She is tall, with dark brunette hair, and fit with an athletic body. She is very in-tune with her sexuality, too. She made it clear from the beginning that she liked me but, despite that and all the fun we were having, wanted to keep things casual, open, and noncommittal. Frankly, I was impressed with how she was so upfront about her stance and feelings and I agreed to keep the outlined arrangement. She suggested that we both go get tested for STDs and clarified that while she does routinely take birth-control, she would appreciate it if I used condoms, and to those things I also agreed. Things have been working out great for several months; we are good friends that fuck and that is all it needs to be. Then, the following happened about a month ago.
