Since finding out she was pregnant, your partner might have been reacting to you differently during sex, or avoiding intimacy altogether.
It might seem like she’s aroused less often or less attracted to you. Aside from simply missing something that you enjoy, sex an important way to feel closer to your partner. Without it, you may worry that you will struggle to stay close.
While it might feel like it, a lack of sex during pregnancy is not a personal rejection. A quarter of new dads say they’re worried that their partner may no longer be interested in having sex  but it’s important to recognise that a decrease in sex during pregnancy is normal, and not your fault.
Your partner may be experiencing a decline in libido. This is very common during a time of changing hormones and physical discomfort like backache and water retention.
Bear in mind that 22-50% of pregnant women experience painful intercourse, and reaching orgasm becomes progressively more difficult as pregnancy goes on [b]. Sex may have become a stressful experience for your partner.
On top of this, about a quarter to a half of pregnant women feel less attractive during pregnancy, and only 12% feel more attractive , so your partner may just not be feeling as physically confident as she’d like to.
Be open and honest with your partner. Talk about your concerns and tell her that you want to be supportive. If she is worried about her changing body, you can reassure her that you still find her desirable, but the most important thing is to respect her needs and desires.
If she is experiencing a loss of libido, remember that this has nothing to do with you as a sexual partner. It might be helpful to discuss this article with her – talk about how these are common changes that couples face all the time during pregnancy.
Up to half of women and at least a quarter of men worry that having sex during pregnancy will harm the baby in some way .
From a medical point of view, there is no reason to ‘forbid’ sex for the majority of healthy pregnant women and their partners, even in the last weeks before the birth . If you’re not sure whether you fit into this category, seek advice from your doctor or midwife.
Remember also that anxiety around sex isn’t always rational, and your partner may find it difficult to shake the fear. If that’s the case, try other ways of being intimate. You may find that other kinds of sexual activity that don’t involve vaginal penetration are a bit easier but, if not, things like hugging, kissing or massage can all help you feel closer to each other.
Don’t expect things to pick back up again too soon after the birth. Your partner will need time to recover, and you might soon sense another obstacle to your sex life – fatigue. Irregular sleeping patterns, feeding schedules, nappy changes, and constant attention to the baby will probably continue to get in the way of your sex life.
You might want to consider asking a family member or close friend to take care of the child for a while so you and your partner can spend some time together as a couple. If you’re used to having spontaneous sex, this might seem a little too regulated, but it might be a start.
Finally, try to remind yourself that it’s not forever. As your child settles into more regular patterns of sleep, you’ll begin to find that there are more chances to be intimate without being interrupted by a crying baby.
