I have said this before and I will say it again...
YOU CANNOT GET HIV FROM SITTING ON A TOILET SEAT...for this to be even remotely possible...the person who used the toilet
IMMEDIATELY before you would have had to blown a load on to the seat and
YOU would have to the sit on the cum with an open bleed cut on your arse cheeks and even then infection is not a given. But think of the logics...would you actually stand outside a toilet waiting for someone to finish beating off while you stood there with an open bleeding cut on your arse cheek.
The 6 months window period for testing is only something that is used in the US...in Australia we use a three month window period.
I am currently in the process of re-writing the STI/STD link in Health and Wellbeing
http://www.justusboys.com/forum/showthread.php?t=171378 which will cover all of the major STI/STD and will include an FAQ on HIV/AIDS.
The main thing is to always
PLAY SAFE.
