Anal

The risk of STIs is markedly increased in anal ejaculations. 

In 2004, in a much publicized case, 

1. novice pornographic actress Lara Roxx contracted multiple infections, including HIV, from Darren James while filming a scene featuring an anal creampie. 
2. James had contracted HIV from having unprotected anal sex with a woman while on a trip to Brazil. He had tested negative for HIV after his return from the trip, and infected three out of 13 actresses he worked with before testing positive in a subsequent test and ceasing to perform.
