No. Arbitrary (casual) sex happens regardless. And have been happening for as long as we can remember. If anything, finding a cure for AIDS will make for a better society since there wont be too much stigma towards people with AIDS, which I think is a much bigger issue than the disease itself. Sex will happen without encouragement, it's coded in our DNA. It helps everyone more to educate one another to practice safe sex as well as the respect of consent as that will make for a better society than making it a taboo subject.
Don't get me wrong, I come from a conservative South East Asian society too. But I know that allowing conversation on "sensitive" matters like these are far more helpful. People will have sex no matter what, trying to stop other people from doing it is futile. It's much more damaging to keep it under the lid than regard it as casual. Education spells the difference between 2 teens trying out safe sex and teen pregnancy which damages the society in the long run.
On another note, your question represent a logical fallacy called the Slippery Slope fallacy, which is one of the errors on logical reasoning, Where you assert that "If A happens, then Z will happen too. (Therefore A must not happen)". You can learn more about Logical Fallacies to help yourself be better at reasoning with yourself and others. Don't worry, we all commit logical fallacies sometimes.
Yes. People will still have sex. And do. Google "swinger clubs" or "seedy bars".
Attempting to stop people from doing such only drives such behavior more underground and reduces chances for testing and prevention of STD transmission.
(Just as an aside, condoms are not 100% effective)
The biggest issue right now is that there is not enough stigma in regards to being a non-tested person. Everyone even if only occasionally having any type of encounter (condoms or not) should be getting full and correctly done STD screenings every 3 to 6 months. (Where full means multiple diseases checked for and correct means including both throat and anal swabs)
In regards to the statement about "a cure for HIV" I would like to point out that at this time we do have a major weapon against at least HIV type 1 spread called PrEP. There is a pill which if taken once a day, (and you can't skip doses), which is effective > 99.9% at preventing infection. If this were made more widely available, in combination with much more regular testing, while the disease wouldn't be cured or eliminated, the rate of infection could be dropped dramatically. See https://www.out.com/news-opinion/2017/1/13/massive-drop-london-hiv-rates-likely-due-buying-prep-online Note: PrEP is recommended for either sex and for any sexual orientation.
