12 Common Sex Injuries You Should Know (And How to Avoid Them)

Sex Injuries: While sex is usually fun and pleasurable, it also comes with its share of risks—some more painful or embarrassing than others. Although sex-related injuries are not extremely common, when they do happen, they can be serious enough to require medical attention.

Here’s a rundown of 12 sex injuries that can happen to you or your partner—and most importantly, how to prevent them.

1. Fracturing Your Penis

It may sound impossible, but yes—you can “break” your penis. This happens when the erect penis bends too far, usually during positions like cowgirl. It causes a painful tear in the tissue and can lead to swelling, bruising, and a loud cracking sound. Immediate medical attention is necessary.

Avoid it by: Going slow with intense positions, and communicating with your partner during movement.

2. Masturbation Injuries

Too much friction or roughness during solo time can lead to skin irritation or cuts. Using improper tools or excessive force can damage sensitive tissue.

Avoid it by: Using lube, being gentle, and giving your body rest.

3. Tearing Her Hymen

The hymen may tear during sex even after a woman is no longer a virgin. This may lead to minor bleeding or discomfort, especially if she hasn’t had sex in a while.

Avoid it by: Taking it slow, especially during penetration, and ensuring she’s relaxed.

4. Microtears in Her Vagina

Lack of lubrication during sex can cause tiny tears in the vaginal walls, leading to pain or burning sensations afterward.

Avoid it by: Prioritizing foreplay and using lubricant, especially if there’s dryness.

5. Infections

Sex can introduce bacteria into the urethra or vagina, causing urinary tract infections (UTIs) or yeast infections. Also, switching from anal to vaginal sex without cleaning up can increase risks.

Avoid it by: Peeing after sex, maintaining hygiene, and using protection.

6. Rug Burns

Getting intimate on the floor or rough surfaces can leave friction burns on your back, knees, or elbows.

Avoid it by: Using a blanket or staying in bed to keep your skin protected.

7. Restraint Burns

Using ropes, handcuffs, or ties without proper knowledge can cause burns, cuts, or bruises around wrists and ankles.

Avoid it by: Using safe BDSM tools and learning basic restraint safety.

8. Head Trauma

Sex near hard surfaces or in slippery places (like the shower) can lead to bumped heads or falls, causing mild to serious injury.

Avoid it by: Being mindful of your surroundings and avoiding overly acrobatic positions on unstable ground.

9. Throwing Out Your Back

Strenuous positions or poor posture can strain your lower back, leading to muscle pulls or spasms.

Avoid it by: Keeping your core strong through exercise and choosing positions that are comfortable for both partners.

10. Assorted Bites and Bruises

Intense sex can sometimes result in unintended marks—biting, sucking, slapping, or spanking can leave visible bruises or hickeys.

Avoid it by: Keeping communication open about limits and intensity.

11. Candle Wax Burns

Dripping candle wax might seem sexy, but regular candles burn hot and can cause real injuries. Wax burns can blister skin and cause lasting damage.

Avoid it by: Using low-temperature massage candles specifically made for safe play.

12. Getting Things Stuck

Emergency rooms report many cases of objects stuck in vaginas or rectums, from bottles to household items. Items without flared bases or proper design can get lost internally.

Avoid it by: Only using body-safe, purpose-built sex toys, especially for anal play.

Conclusion

Sex doesn’t have to be dangerous, but being aware of the risks can help you avoid painful or embarrassing experiences. By communicating, using the right tools, and staying cautious, you can enjoy safer, more comfortable sex.

Always listen to your body, and if something doesn’t feel right—stop. When in doubt, don’t hesitate to see a doctor.
