"There’s almost no risk of pregnancy from fingering or hand jobs. If a person has dirty hands and touches another person’s genitals, they can spread germs or bacteria. It’s possible, but not likely, to spread a sexually transmitted disease (STD) this way. However, there’s a very small chance of starting a pregnancy if semen gets on one partner’s finger and that finger is put immediately into the vagina. It’s a good idea to wash hands before and after any sexual contact."
"Oral sex may lead to the woman developing throat cancer due to the Human Papilloma virus (HPV), the same virus that causes cervical cancer. If the man is already infected with the virus, there is a high risk of the partner developing throat cancer if they engage in oral sex. The symptoms of cancer may take a short time to show if one is a smoker or takes alcohol because these substances increase the risk of developing the cancer. If the woman has HPV and the man engages in oral sex, he also may develop throat cancer."
