can oral sex cause hiv or aids?

Answer 1

Oral sex can not CAUSE HIV or Aids, but it can be transmitted, if done without protection. When there is a trade of bodily fluids (such as semen, and blood that already contain the virus) then yes you can contract HIV.

Answer 2

Sex does not causes HIV, nor does oral sex.

HIV is a virus. Infection is transmitted when you come in contact with someone who has the virus and there is an opportunity for the virus to enter you system.
