What do I need to know about having sex during and after pregnancy?


In our society, pregnant women and mothers often aren’t thought of as ”sexual,” but women are sexual beings at all stages of their lives. Pregnancy is a time of change and adjustment that affects every part of a woman's life, including her sexuality. As these changes happen, there are many ways for pregnant women to experience sexual intimacy. Communication between partners is the key to making sure that sexual relationships are comfortable and satisfying, especially during pregnancy.

Is it safe to have sex during pregnancy?

Yes. Sexual activity during pregnancy is healthy and safe, unless your doctor or midwife has told you otherwise. You may be advised to not have sex if you:

  • have miscarried before
  • have bleeding in the first trimester
  • have a low-lying placenta
  • have a history of premature labour
  • have a lot contractions in the last month of pregnancy.

It's also important to think about protection from sexually transmitted infections (STIs) during pregnancy. If either partner has an STI, is HIV-positive or has had other sexual contact outside the relationship, practising safer sex is recommended. Talk to your health care provider for more information about the safety of sex during pregnancy.

Does sexual desire change during pregnancy?

It can. Physical and emotional changes during pregnancy can affect pregnant women's desires and comfort levels. Every woman is different and every pregnancy is different. Some women feel more attractive and enjoy sex more during pregnancy. Others have little or no interest in sex during pregnancy. A woman's partner may experience changes in desire as well. It's important for partners to talk about these changes and how they feel.

What are some common changes that might happen?

First trimester

  • Parts of the body, such as the breasts, can become more sensitive. Some women find this uncomfortable while other women find it pleasurable.
  • Morning sickness or feeling tired and uncomfortable can also make women less interested in sex.
  • Throughout pregnancy, air should not be blown into the vagina during oral sex to avoid complications.

Second trimester

  • Pain and discomfort such as backaches and soreness around the breasts and belly may affect sexual desire.
  • For many women, sexual desire increases during this stage of pregnancy.
  • Stimulating the breasts can cause colostrum to come out. This is normal.
  • Partners may have to try different sexual positions or activities to discover those that are most comfortable and pleasurable.

Third trimester

  • Feeling tired, feeling ”big” and having concerns about giving birth can decrease sexual desire.
  • A woman might feel the fetus move after she has an orgasm.
  • As the fetus moves into the pelvis in the 9th month, vaginal penetration may become uncomfortable.

Can having sex make me to go into labour?

Pregnant women often have mild contractions during arousal and orgasm, but these contractions aren't powerful enough to start childbirth unless it's already time.

Nipple stimulation and intercourse are sometimes used to help start labour when a baby is overdue. Sperm contains a small amount of a hormone-like substance called prostaglandin, which softens the cervix and may help start labour. Women who are at a high risk of going into early labour may be advised to avoid orgasm, nipple stimulation and intercourse, or to use a condom for intercourse to avoid putting the uterus in contact with sperm.

When is it okay to start having sex after the baby is born?

This depends on the desire and comfort level of each woman. Interest in sex may decrease and sex may be painful for some women after childbirth because of:

  • feeling tired from caring for a newborn
  • physical discomfort
  • less vaginal lubrication
  • hormonal changes.

Doctors often recommend waiting about 4-6 weeks before having intercourse. When bleeding (lochia) stops, it shows that the cervix is closed and that, physically, intercourse is safe.  It's also important to wait until any tearing, episiotomy or caesarean scars have healed. Again, it's important to keep the lines of communication open between partners. A woman should do what feels right and not feel rushed.

What else should I know about sex and intimacy after childbirth?

Breastfeeding:

Breastfeeding can often cause feelings similar to sexual arousal or orgasm. Sometimes breastfeeding causes vaginal dryness. Using a water-based lubricant can make vaginal stimulation more enjoyable.

Birth control:

You can get pregnant soon after giving birth, so it's important to think about birth control. Many different birth control methods can be used post-partum, even by women who are breastfeeding. It's a good idea to talk to your health-care provider about post-partum birth control before the baby is born, so you have time to think about your options.
