Megumi_sama: Just an intro, I'm 18 years old, senior in high school, 6'3, 250 lbs, muscular, virgin (not that it's anyone's business...), and I'm not really "big" (6x5.5, so slightly girthy but not long.) I've talked to several girls about this, including my girlfriend, and they all agree that what I suspected did happen. However, no one was able to offer any suggestion why it happened. I was hanging out with two girls who are my friends at the mall. One is fine with my silly personality: I often tickle and poke girls I'm friends with in a flirty way, but would never cheat on my girlfriend. The other, however, can't stand it. She does not like having physical contact with me at all, it seems, not even feeling comfortable hugging me (she's fine hugging the rest of the guys in the group.) Anyway, we're walking around the mall, and she's slightly ahead of me to the right, looking back and down towards me staring while all three of us talk. I think nothing of this. When I get home, I realize that my penis was bulging down my left pants leg, which had never happened before since this was a tight pair. This was unforunate, as the bulge was very pronounced, you could make out the head even. I know many will think I'm just boasting, or trying to pass off intentional showing off as an accident (I honestly don't know how I didn't realize I was visible). I just want to know if you agree that she was staring at my bulge, and if she was, why? She's made it apparent on numerous occasions that she has no intrest in me physically or sexually (she's a former crush who did not have feelings in return), but just interested in me as friends.
