3 things required for HIV transmission to take place

Hi, welcome to the ehealth forum and I am glad to help you.
You seem to be concerned about the risk of transmissiom of HIV through different modes and under different conditions.
In order for infection to occur, three things must happen:
1.You must be exposed to pre-cum, semen, vaginal secretions, blood or breast milk, AND
2.The virus must get directly into your bloodstream through some fresh cut, open sore, abrasion etc., AND
3.Transmission must occur, directly from one person to the other, very quickly (the virus does not survive more than a few minutes outside the body).


First, the contact of sperms of the guy with the cuts on your right hand poses a definite risk of transmission of HIV to you if the guy is infected. For cuts, once a scab forms (usually within a few hours), this would no longer give access to the bloodstream, preventing HIV from entering. Of course, the deeper the cut, or the more severe the damage to the skin, the longer it will take for healing to take place. Not every one heals (and therefore produces a scab) at the same rate, so nobody can give you an exact amount of time it would take for a cut to heal, or for a scab to form. But the larger the cut, the greater the amount of time it would take for a scab to form, and for the cut to heal. Let me repeat that the amount of time it takes for a scab to form, and for a cut to heal, can vary from person to person.

Secondly, giving oral sex also poses a definite risk of contacting HIV if the guy is infected since pre cum contains HIV virus. The more of these body fluids you are exposed to, the greater the risk of infection there would be. If you have any open sores, cuts, abrasions or gum disease in your mouth, the virus can get into your bloodstream. The risk is less than if you had vaginal or anal intercourse, but the risk is real, and transmission can occur. There have already been reported cases of HIV infection specifically through giving oral sex. In addition to HIV, while giving oral sex, you could also be at risk for other sexually transmitted diseases (STDs) including herpes and gonorrhea and even syphilis.

Thirdly, unprotected sex poses a even greater risk for HIV transmission for the risk is even greater than that with semen touching a hand with cuts and with oral sex. The amount of fluid that the human male issues varies widely among individuals. Some men do not produce any pre cum, while others emit as much as 5 mL. There is no evidence to show that a man does not precums again once he has fully ejaculated. So the practice of safe sexual practices should be encouraged.
Hope this helps. Take care.
