Dear Ren,
Never be hesitant to ask. The problem and the reason that many get kind of hostile on this one (sometimes including myself) is that over 30 years after this disease or disease process was found and then labeled we still have people who do not know.
Working for years around the entertainment industry I personally attended over 50 funerals. Most of those friends and acquaintences I buried were infected before we know anything.
Nearly a whole generation of gay men fell victim to something that they could not control and something that had been waiting in the shadows to get them. In my case the men I buried worked in music, costume design, set design, props, administrative positions, and some were also found in front of a camera.
In addition, many in the industry lost children. Those who lost one or more children included Russell Johnson (Gilligans Island's Professor) Harry Morgan, (MASH's Colonel Potter) Robert Guillame (Benson/SOAP) and more.
Performers lost have been too numerous to even mention.
Yet to this day we have a retrovirus which can be totally eradicated. It can be eradicated by using common sense. It can be eradicated through education and this virus is no longer a scourge of the gay community it is now everywhere.
As I am writing this there are individuals out there barebacking, there are individuals of very young ages who are "bug chasers" trying to become infected, and there are individuals presenting deliberate and false information to promote a personal agenda.
It has been said by another that the biggest enemy when it comes to STD's is not the disease but the brain of the participants in the sex acts involved. There are times that we think with the heads of our dick and not the head on our shoulders.
The question you asked is absolutely legit, but what you asked has become a point of great anger and frustration for many of us. It has become this because no matter how hard we try, there are people who simply cannot seem to get the message.
Remember something else. When you are really well educated in this subject you become an educator. You personally may have the ability to save a life. You may be the one who teaches thinking with a brain instead of a libido.
Education is NOT abstinance. Education is understanding not only HIV, but the rest of the dangers out there and preventing them. It is also knowing what questions to ask.
Good Luck my friend!
