Over the past two years I have had sex with 26 street walking prostitute's in Mexico, US and UK, 20 of these were male. All encounters I used a condom and as far as I'm aware the condom did not break.
I have read that the condom has around a 98% protection rate against HIV, what is the 2%? Is this when the condom actually fails and splits? Would I know if a condom had failed during anal intercourse?
I have become very unwell lately which is why i'm asking this.
