I have just searched, and could not find a single case of anyone getting HIV via spunk in the eye, ever. Ditto for Hep of any kind. It is a theoretical risk rather than a common one, whereas infection rates for unprotected vaginal or anal sex are much more concrete.
Chlamydial conjunctivitis is more common, but easily treated with antibiotics, as with oral or genital chlamydia.
If YOU don't want to offer facials, then don't. Lots of escorts don't. I like them, so I offer them.
"The estimated annual number of needlestick and sharps injuries in the United States is around 385,000. These injuries may expose healthcare workers to more than 20 different bloodborne pathogens, the most important of which are hepatitis B virus, hepatitis C virus, and human immunodeficiency virus (HIV). All blood, body fluids, secretions, and excretions, except sweat, can contain transmissible infectious agents. The risk of developing HIV after a needlestick injury is about 0.3% (after a splash 0.09%), the risk for hepatitis B is 6% to 30%, and the risk for hepatitis C after a needlestick is about 1.8 % (much lower after a splash). The following circumstances increase the risk of infection:
A hollow-bore needle caused the injury.
The area of exposure was penetrated deeply.
Blood was injected during the injury.
The patient has a high viral load."

Actually getting body fluid in the eyes is something of concern for health care providers.
I remember an episode of House where one of the doctors working with House got a splash of blood to her face from a HIV positive patient, and there was a drama around that for that and the next few episodes because she didn't knew if she was infected.
There are plenty more articles and posts in nursing forums about this subject.
