Has anyone ever ever caught HIV from giving a man oral? No sex just oral ?

Answer 1

No, I haven't and been tested for HIV. After having a partner that fooled around on me a lot .. by some miracle I don't have HIV. 

Answer 2

Of course.

HIV is caused by fluid transfer

(from an infected person to a non-infected person).

There are even cases of people contracting HIV from their DENTIST

(non-sexually)

because of oral fluid transfer.
