So when you give a handjob, a few things matter - first, the skin
on your hands is too thick for the
virus to infect. If there is
virus on your hand, after the movement, the exposure to air, time, touching other things, etc., it degrades enough that it is unable to infect anything.
Effectively, it dies and is unable to infect.
If you touch an outbreak, don't touch your eyes or mouth or nose immediately after. That's all you need to worry about.
