(I'm surprised I haven't posted here; I've been subscribed since the beginning, but none of my stories are nearly as interesting as Armaegis'.)
I'm blanking on your age even though I'm pretty sure you stated it earlier here, but for some reason, 15/16 is sticking out, I hate to be that guy, but at that age (huh, that's kind of weird to say because I'm not that much older than you) I'd definitely give it a little more time before actually like...doing it. Even though you seem closer than most couples I know, it's definitely not something to underestimate. My first time freshman year of high school, with someone that I still consider the single most important friend I've ever had, led to some serious mental issues later on, and even now, four years later because at that age, it's harder to understand exactly how sex can screw with your mind if you go into it with a certain mindset. From experience, the mind interprets a significant difference between one night stands and relationship-bonding sex, and the latter obviously leads to a completely new level of closeness, which can be pretty scary.
^^That was totally just rambling that probably doesn't make sense; I can rephrase that later if you want. I'm just procrastinating studying for a midterm so my mind is kind of frazzled.
I also feel kind of obligated to share a story, but the only one that's even relatively thread-worthy is this one:
So I went to an event with a friend, and when we got there, my friend met up with one of her friends. She introduced me to her friend and I kind of felt something click, and we spent most of the event talking to each other and she seemed really nice, so I offered to walk her back to her dorm. When we got back, her roommate and her friends were being especially loud, so she asked if I wanted to see a movie with her as an excuse to leave the room. I thought, "Awesome, she didn't think I was creepy!" We ended up watching a rom-com of some sort, which was a great time all around. After walking her back again, I definitely though I had a chance with her until in the middle of one of her stories, "...yeah my boyfriend..."
But we're pretty good friends now so...it's really not a "worst date story" because, hey, at least I didn't do anything stupid.
