My boyfriend and I mutually masturbated with each other and he ejaculated…

…but our hands went from our own genitals to each others’ genitals afterward. But his penis never went into my vagina. Is there any chance we could get an STI or become pregnant?

This is a great question. Let’s start off by saying that mutual masturbation can be a low-risk way to express sexuality. With that being said, there are precautions that someone would need to take in order to reduce their risk of STI transmission and/or pregnancy.

Any time someone comes into contact with one or more of the four modes of transmission, they can be at risk of STI (or sexually transmitted infection) transmission.  The four modes of transmission are…

  • Blood
  • Skin to skin contact
  • Sexual fluids (semen and vaginal fluids)
  • Mother to child (breastmilk and vaginal delivery)

In order for someone to contract an STI, they would need to engage in sexual activity with a person who already has an STI in which one or more of these modes would come into play.

Because you or your partner may have had sexual fluids on your hands before touching each others’ genitals, risk of STI transmission can be possible. Risk of transmission this way is less common, but can happen.

As far as pregnancy goes, if semen was on either person’s hands and could’ve come into contact with the vagina, pregnancy could be a possibility as well. Again, risk of pregnancy is less likely this way, but can occur. Any time semen comes near the opening of the vagina, sperm can move into the vagina and cause a pregnancy.

When someone is using their hands or fingers to sexually stimulate someone, it’s very important to emphasize hygiene as well. It’s important to make sure you and your partner are washing your hands with an unscented soap before sexual stimulation begins. If you wash your hands before touching each other, you can wash away any sexual fluids that may have been present before- which can eliminate risk of STI transmission or pregnancy.

Although STIs can be common, remember that they are preventable! Washing your hands, using condoms or dental dams, and using birth control can help drastically reduce your risk of STI  transmission or pregnancy.
