No, you cannot get pregnant from swallowing sperm. Remember, though, if your sex partner has one of the following sexually transmitted infections (STIs), you can get them from oral sex – like herpes, HPV (human papilloma virus), hepatitis B and HIV. Even though we think of these as infections spread by vaginal or anal intercourse, you may also become infected if exposed by oral sex. Best practice – know your partner, make sure he has tested negative for all STIs (never hurts to see his lab results – before you have any kind of relations!), and use a condom every time, even with oral sex.
