Welcome to the forum. The exposure you describe is zero risk for HIV and minimal risk for other STDs. Condom protected sex is safe sex, as is masturbation. That you may have licked your finger following masturbation of your partner does not change this. As for your specific questions:
1. Your neutrophil count, while a bit low is a non-specific finding and not something to be concerned about. It certainly does not suggest HIV. Many totally normal people have somewhat low neutrophil counts. You are just one of such people and should not worry about this.
2. You do not need testing for your exposure because the risk of this exposure is zero. There is no medical reason related to this exposure for you to have an HIV test.
3. HIV infection is a chance event for persons exposed to an infected sex partner. The likelihood of HIV transmission is higher when a person is exposed to higher concentrations of virus. Most exposures to HIV, even when a partner has a large amount of virus present does not cause infection. The virus to which people are exposed to, if it does not cause infection, does not remain in the body but is eliminated by the body.
Hope these answers help. Because of Forum rules and the fact that you have posted on the wrong site, there are no follow-up questions permitted. That should not be a problem for you however since you are not at any risk for HIV from the exposure you describe. Take care. EWH
lastly from reading one of the forum, it stated one or small amount of HIV virus is not likely to infect human unless in a bigger amount.
Q3: how human body treats one HIV virus? Is this virus will die or stay in human body
(appologies from unclear original question Q3)
