I'm in agreement with the opinion of others here. No chance of getting HIV through acne and semen. First of all, the bleeding pustule is probably exudating, meaning any fluid is coming out and preventing anything getting in. The moderator is correct. Unless you have an open wound in your mouth, saliva can (no absolute proof) prevent virii from getting into the bloodstream. Again, it's important to know that HIV must get through the mucous membrane and into the blood. That's the only way for it to multiply.
