Hello everybody

I have a doubt ( I´m 17 years old) and I haven´t dared to ask this question before.The question is:

Could a person contaminate a condom with blood or another fluid containing AID using a needle or something like that?

I ask this ´Cos I´ve a contact with a prostitute who gave me a condom. The condom was in its package and seems to be in good shape so I put this one on myself. To tell you the true we didn´t do anything the only thing she performed was a "handjob" and that´s all. Everything seems to be ok but suddenly a crazy idea came to my mind : "perhaps that prostitute gave me a condom contaminated by blood or other fluid containing AID"..."I dont know maybe she used a needle to do that"......I really dont know what to think about it...Im so scared.

Please let me know your opinion about this...I can´t sleep!
Please.......pls.......pls................ Help me!

Best Regards
