Sex During Pregnancy: Is It Safe, Benefits, and Best Positions by Trimester

My partner and I have always shared a strong sexual connection. When we decided to start a family, our intimacy didn’t disappear—though pregnancy did bring new questions and even a little fear. We both worried about whether sex during pregnancy could harm the baby. To my surprise, after researching and talking to doctors, I discovered that sex while pregnant is not only safe in most cases but can also be deeply rewarding.

If you’ve ever wondered “Is sex during pregnancy safe?” or felt unsure about how intimacy might change while expecting, this guide will give you the answers. We’ll cover when sex might not be recommended, the best pregnancy sex positions by trimester, and even what to know about oral sex while pregnant.

Is Sex During Pregnancy Safe?

For most women, yes—sex during pregnancy is perfectly safe and even encouraged. Your baby is well protected by the amniotic sac and strong uterine muscles. That said, every pregnancy is unique, and there are certain situations where a doctor may advise against intercourse.

When to Avoid Sex During Pregnancy

You should hold off on sex if:

• Your doctor has specifically advised against it.

• You experience unexpected vaginal bleeding or have a history of premature labor.

• You have placenta previa (when the placenta covers the cervix).

• Your water has broken (at this point, it’s baby time—not bedroom time!).

Always check with your healthcare provider if you’re unsure.

Changes in Sex Drive During Pregnancy

Many women notice shifts in their sex drive throughout pregnancy. Increased blood flow to the pelvic area and hormonal changes can heighten arousal, making sex during pregnancy feel more intense. At the same time, fatigue, nausea, or discomfort can affect desire.

Don’t be surprised if your partner finds you even more attractive than ever—pregnancy can bring out confidence, sensuality, and intimacy in new ways.

Best Sex Positions During Pregnancy (Trimester by Trimester)

Every stage of pregnancy comes with unique body changes. The right sex positions during pregnancy can help you and your partner stay comfortable while keeping intimacy enjoyable.

First Trimester: Anything Goes

In the first trimester, most positions are safe. Missionary, spooning, doggy style, or experimenting with sex toys (always cleaned properly) are all options. According to Dr. Lauren Streicher, “There doesn’t seem to be any connection between sex and miscarriage in early pregnancy.” This is the perfect time to explore intimacy freely.

Second Trimester: Get Creative

As your belly grows, lying flat on your back may cause pressure on your vena cava (a major vein). If you do try missionary, place a pillow under your hip. Otherwise, positions like doggy style, reverse spooning, or woman-on-top give you more comfort and control. Many couples find this trimester the most playful and adventurous.

Third Trimester: Comfort First

By the final stretch, comfort is key. Positions that avoid pressure on your belly work best:

• Spooning (side by side)

• Woman on top

• Rear entry (from behind)

• Sitting on the edge of a chair or bed

Some women find deep penetration uncomfortable late in pregnancy, so communicate openly with your partner about what feels good.

What about oral sex?

Oral sex has the green light too as long as your partner doesn’t have any mouth herpes since it has been proved this STD can be transmitted to the baby. If your partner suffers from this, try to use a dental dam when he or she is giving you oral sex.

Another essential thing to take into consideration when having oral sex is telling your partner not to blow you. According to Parents Magazine: “in very rare cases it could cause a dangerous embolism (when a burst of air blocks a blood vessel).” Personally, I haven’t heard about couples that do this, but we’re just giving you this valuable advice we have listened to many, many times.

I can say to you, with all certainty, that having sex during pregnancy is safe and amazing. Reassure your partner and enjoy a beautiful time in your lives.

Oral Sex During Pregnancy

Oral sex is also safe during pregnancy, with two important cautions:

1. If your partner has oral herpes, avoid oral sex without protection (a dental dam) since the virus can be transmitted.

2. Never blow air into the vagina—though rare, it could cause an air embolism, which is dangerous.

With those precautions in mind, oral sex can be a pleasurable, safe alternative throughout pregnancy.

Sex during pregnancy is not only safe for most couples but can strengthen your bond, ease stress, and boost intimacy during a life-changing time. Unless your doctor recommends otherwise, there’s no reason to avoid it. Instead, embrace the changes, try new positions, and reassure your partner that intimacy is still very much part of your journey.

Pregnancy is about creating life—but it can also be about rediscovering pleasure, connection, and the joy of intimacy.
