Can You Only Get an STI From Having Sex?

Uncover the facts about STI transmission. Learn about the different ways STIs can spread – not just through sex – and how to keep yourself and your partners safe.

Let’s clear up a common misconception: STIs aren’t just about sex. While many infections are transmitted through vaginal or anal sex, there’s more to the story.

Beyond the bedroom

STIs, or sexually transmitted infections, can indeed spread through various sexual activities – vaginal, anal, and oral sex. But here's the kicker: some STIs can be transmitted without full-on intercourse.

Skin-to-skin contact: Infections like herpes and HPV can spread through intimate touching, even without penetration. So, those steamy makeout sessions aren't entirely risk-free.

Sharing is not always caring: Using contaminated needles or sharing sex toys can also lead to STI transmission. It's not just about who you're sleeping with, but what you're sharing.

The not-so-sexy truth

While less common, STIs can spread through non-sexual means:

  • Mother to child: Some infections can pass from mum to baby during pregnancy or childbirth.
  • Blood transfusions: Though rare in the UK due to rigorous screening, it's theoretically possible.

Remember, many STIs are sneaky and don't show symptoms. Regular testing is crucial, especially if you're sexually active or considering a new partner.

The bottom line

While sex is the main culprit, it's not the only way to catch an STI. Being aware of all transmission routes helps you make informed decisions about your sexual health. Stay safe, get tested, and don't be shy about discussing protection with your partners. Your future self will thank you!
