Why don't doctors explain that condoms don't stop the aids virus?

The virus is to small and can fit through the standard cracks in all condoms. So how come everyone doesn't know that?

An oxygen molecule is many times smaller than an HIV particle.

Try pulling a condom over your head so it covers your mouth and nose, and then try breathing through it. (They stretch).

So why can't the oxygen molecules pass through the latex, given that they're so tiny and the holes are so big relatively speaking?

The answer is that at microscopic levels the size of the gap is less important than the electrostatic forces which prevent particles passing through a gap which is otherwise large. enough.

An intact condom, properly used, significantly reduces the chance an HIV infection will pass from one person to another. It isn't 100 per cent, though.

Because that's not true, that's why doctor's don't tell people that. No one needs another excuse not to use a condom, especially if it's not true.

There is is no guarantes in life so use your head. If a condom can't protect you 100% from pregnancy why would people think you won't get disease when using them!

Because it is not true...

Even if there are cracks - and there shouldn't be in a well-made rubber - condom use reduces the risk of contracting HIV and other STDs - and, c'mon, a reduction is better than nothing!
