The scenario was: a girlfriend from a roommate came over to stay here for 3 weeks. 3 weeks long we just acted normal but i really wanted to try to kiss her but she acted like she wasn't into me in my eyes. The last day before she had to fly back she came into my room and we talked and ended up having sex. She told me that she was waiting for this for 3 weeks already. How can i not see or know this? I'am a really really shy guy tho.
