HIV Transmission? - TheBody.com's Bulletin Boards

Being a senior in high school, many times "peer pressure" can get to you. But I have been blessed with good parents and have been a big factor in my growing up. I have never done drugs, never gotten drunk, and have done great in school. I have scholarship offers to colleges. I am sorry for "bragging", but I thought I would give a background of myself.
But last night, something happened to me that has affected me greatly. Since I have not engaged in any sexual activities, I really am not very familiar with HIV and how it is transmitted.
I was at a party last night and was having a good time. Towards the end of the evening, my keys fell out of my pocket and fell into the couch. While looking for them, I felt something sharp poke me. When I pulled my hand out, I noticed that I was poked with some type of a pin or something that is used for sewing. Once I pulled it out, I noticed there was a little bit of blood on my hand where the pin went in. Not a lot, just a little bit. I thought nothing of it. A few minutes later, a friend of mine said that she was reading that someone could get HIV by being poked with a needle. When I asked her about whether she was sure about what she read, she said, "Well a pin is sharp and if blood was drawn from being poked, then you could get it if the situation was right." That really scared me. I don't know how long the pin was there and I don't know where it was or how had it before it ended up there. What really worries me is that a lot of people sat at that couch, and some of them are sexually active and have unprotected sex, which I know can transmit HIV. Maybe I am reading way too much into this, but this really has worried me.
I guess my questions are: Do I have anything to worry about? Do I need an HIV test? Has HIV been transmitted by being poked or cut with a pin or thumb tack?
I have set high goals for myself in life, as I want to go to college to be a lawyer or possibly an engineer. I am saving myself for the right guy as far as sex goes. I just hope that I did not become at risk for HIV from last night.
The reason that I came here is that I heard a year or so ago that this website has a place to go to talk to people who can offer support and give good information and feedback about possible HIV trouble. I am hoping that this is true. Any information or support that you can give me will be very much appreciated from this teen.
I am sorry that this is so long, but once I get started, I tend to be long-winded.

Sincerely
terrifiedteen
