One thing that you fail to take into account with an HIV test is that they're only really accurate to within the last 3 months on the most part. All it takes for the virus to be passed on is one single night of fun, without taking the proper steps. Take it from someone who is now HIV+ because they trusted the wrong person… One night of fun isn't worth the lifetime of problems that it can cause. Always assume that they are poz unless they are a monogamous life partner that you have grown to trust over time.
Not to mention, if you're having some random hookup with someone, you have to take into account that you're probably not the only person that they hook up with. For this reason alone, you can get caught with a surprise at any time, unexpectedly. While on this topic, I bet that you didn't know that over 60% of people who are newly diagnosed with HIV didn't even know they had it. In a case such as mine, you can think you're safe, but later come to discover that you had been carrying HIV for almost a year before you even knew about it, all because you trusted the wrong person.
Bottom line people... No love without a glove. I know I may sound like a broken record by repeating that over and over, but if you truly understood the mind f*** that it puts you through, along with the cost of the medications ($1533.53/mo just for the ones that keep me alive, much less the ones that deal with their side effects), the side effects of the medications, the chronic body aches in some cases, along with a number of more interesting things like discovering that your body will do things that you never thought possible, you would truly understand the importance of why it's just not worth it. You may want to do yourself a favour and re-think that policy of "trusting" someone before its too late. Don't get caught in the same trap that I did.
Another little food for thought... When you become HIV+ and go through that whole stage of mental instability (and trust me... it WILL happen no matter how educated or "prepared" for it that you are) and truly understand what it's like to be HIV+ in every regard, then you'll know what it's like to live with the burden of knowing you passed HIV onto someone all because you didn't know you had it. That's a guilt that you can never get rid of and will haunt you for the rest of your life (especially when that person commits suicide when they find out).
You may think that I'm just talking smack, but for those of you who don't know, take these words of advice from someone who has known that they're HIV+ since they found out on March 20, 2009 (almost 2 and a half years ago). I know of what I speak and sincerely hope that you don't make the same mistake that I did.
