not sure what a table shower is but I'll answer the same as your other questions you posted as an excuse to type the word penis.
The virus itself does not just lay around waiting to pounce on someone, it can not live outside of its carrier (blood.) There's no such thing as a little pile of HIV. It is sexually transmitted, not something like the flu or cold which is air born. It has to be transmitted by a fluid.
Depending what a "table shower" is (it sounds nasty so I'll presume the worst) you have a higher risk then your bed in the last question I answered. But HIV has to be carried in some sort of bodily fluid. And it has to enter your body in some fashion, it can not pass through your skin without some break in the skin.
But, I've seen you other questions... this is just an excuse to be immature.... grow up.
