Brother...
I'm not from medical field. But we all have learnt basic science in our school/ college days.
As per my knowledge HIV can't be transmitted through Saliva, Sweat, Skin touch. It can transmit through other body fluid like blood, semen, breast milk vaginal fluid.
So, your point is wrong...? Na.....
It is partially wrong
It can't be transmitted if both kissers maintain proper oral hygiene.
But SB girls have habit of chewing gutkha. Which leads to ulcers, sore, bleeding gum problems. And if mongers have same issues. Then through blood contact while doing DFK with HIV positive girl, chances of getting HIV is high. Forget HIV what if she has other STDs ? What if she gives BJ to STD bearing person at 3'O Clock & does DFK with healthy monger at 4'O Clock.
Anyways it is a risky game... Attaching a pic of one of the oral STDs
