For some, penetration during sex is even more enjoyable when it’s very deep. Not only can it feel good physically, but it may also be emotionally satisfying as it brings bodies very close together.

Deep penetration can be either vaginal or anal and usually involves penetration with a penis or dildo. Following a few safety precautions can help minimize discomfort. 

Deep penetration is sometimes also called cervical penetration. This is because deep penetration into a vagina can sometimes feel like the cervix is being penetrated. However, cervical penetration is not possible. Outside of childbirth, the cervix remains very small.

Some people believe that deep penetration is dangerous. With enough lubrication and patience most people can enjoy deep penetration without pain or injury

If deep penetration sounds appealing to you, there are a few ways to explore it safely. If you would like to be penetrated, you may consider exploring your body on your own before trying this with a partner. It’s possible to try deep penetration on your own with a dildo or sex toy and a water-based lubricant

While trying deep penetration on yourself, take as much time as you need. Your body may need time to adjust or stretch to accommodate the toy. Taking things too quickly can cause pain or even injury. Deep penetration should not hurt; if it does, slow down, use more lube, or try a smaller toy. 

When trying deep penetration with a partner, communication will help both of you have a good experience. You may need to slow things down, or try several positions to find one that is comfortable for both people and allows for deep penetration.

Penetration shouldn’t be painful. If it is, you may need to use more lubrication, spend more time stretching, choose a different position, or simply stop. Deep penetration can lead to bruising and even internal tears if you ignore pain. Check in with your partner often to make sure you're on the same page. Get a clear "yes" before continuing.

Only use a dildo or sex toy that’s designed for penetration. Don’t use other objects as they may get stuck or cause pain or injury.

Pay close attention to your partner’s signals. Always listen and be prepared to stop if you notice pain or discomfort.

In some cases, particularly deep penetration of the vagina can lead to mild spotting or bleeding. This is generally the result of hitting the cervix and occurs for the same reason that spotting may occur after a pap smear. It typically resolves itself in a few hours and is nothing to worry about. You may also have bleeding after anal penetration due to the sensitivity of the tissues in the area. However, if discomfort or bleeding continues for more than a day or two after anal or vaginal deep penetration, call your doctor.
