Dear Sir, My question to you is that can HIV be infected by having sex with multiple partners but there status is negative??
One more question is that my doctor told me once that I would infected if the women with whom I had sex with has 3 childrens then I would get infected?
And can a women have sex with lot of people and still remain Negative because all the partners are HIV negative?
I spotlight this question here because it is indicative of some of the unfortunate information that has been communicated in the wider community, and demonstrates to me how some doctors continue to be the most abhorrent perpetrators of dangerously unscientific information. This is certainly not the first time I've seen this happen, and I'm sure not the last.
So let's be clear first about one very important thing: You must have HIV to transmit HIV. If you are HIV negative you do not have HIV and cannot give HIV to others (http://www.thebody.com/content/30024/hiv-transmission.html).
Let's be clear about the next important thing: People who are living with HIV who are undetectable for six months or longer also cannot give HIV to others. Once the virus has been suppressed for a sustained period of time, it is considered to be "untransmittable" or "negligible" (http://www.thebody.com/content/79994/hiv-undetectable--untransmittable-interview-with-b.html).
Having multiple sexual partners does not change the science. If I have sex with 100 people who are HIV negative, or undetectable, I am at no risk of acquiring HIV. If I have sex with one person living with HIV and detectable, without using any protection offered from condoms or PrEP, then I am at acute risk of becoming HIV positive.
Having children does not in any way increase one's chances of acquiring HIV. Any professional who claims this is so deserves to be reported, investigated, and removed from any platform where they can hurt people and lie in this deplorable manner.
Addressing your last question, a woman can most certainly have sex with a lot of people and remain HIV negative. If her partners are HIV negative, she is at no risk. If her partners are HIV positive and undetectable for six months, she is at no risk. If she chooses to use PrEP for protection she is at nearly zero risk. If her partners use condoms 100% of the time then she is at significantly lower risk. Any of these prevention methods alone of combined allow people to enjoy sexual pleasure and intimacy with little to no risk of acquiring or transmitting HIV.
I hope these answers allow to use facts in your sexual decisions. I also sincerely hope you consider finding a doctor who actually practices medicine over morality, who knows science over stigma.
