What are some real info about Scorpios?

Ok I believe in astrology because the traits describe me completely. Like whenever a guy asks me what my sign is and i say scorpio, they get scared and think i'm going to kill them or something ha ha. Look i like fighting but i wont kill every person i se ha ha. Also whenever a girl i'm dating asks me they get like horny for some reason when i tell them. I just want some of you to tell me real qualities and symbolic things such as zodiac stone, animal, etc. Also i was thinking of getting a men's scorpio pendant, if any of you know where i can find one that's around $20-$30 that is either black or some form of silver/gray that would rock!
