Can I get the HIV infection if oral sex was given and no semen or other body secretions was involved?

HIV transmission. The risk of HIV transmission is highest with IV blood transfer (i.e.:blood product/shared needle) but as well can be transmitted sexually. Highest sexual risk is male to male or male to female (20x female to male). Lower risk is transmission with deep oral sex, especailly if the recipient has oral lesions or cuts or unknown microabrasions. Even w/o ejaculation there may be some semen spill.
Potentially. Penile microabrasions (minor cuts/abrasions) are more common in uncommon sex practices (oral/anal) that may cause small (invisible) blood droplets land on the partner's mucosal membranes. This may lead to infecting the partner of the HIV + individual.
