handjob hiv risk from sw was started.
And then wat happened...did ya get it treated...is it extremely dangerous...

I do not think you need to be concerned. Touching is simply not a way to get HIV or other STDs. The scenario you describe is not a low risk exposure--it is a no risk exposure. STDs are spread throuh the transfer of secretions from an infected person to a non-infected person. The thick skin of the hand is not susceptible to infection by STDs. Even if she had touched others at some time in the past, for her to have then contaminated you is just not plausible. Do not worry. Try to get some sleep

Also the other extreme circumstance I was thinking of is maybe she still had some other guys residue on her hands from before and then touched mine but I highly doubt it.
