Now that you're pregnant, "safe sex" takes on a whole new meaning. Is it safe to engage in sex while pregnant, especially toward the end? What positions are safe and comfortable? Are there any practices to avoid?
Happily, most women who are healthy and having a normal pregnancy are cleared to have sex until their water breaks or until labor starts. Your uterus is strong and out of the way. The amniotic sac is made of top notch materials, and the whole package is sealed tight with a thick mucus plug, which guards against infections. Your partner can't hurt the baby's head, break the bag, or rupture the cervix during intercourse.
An orgasm can cause mild uterine contractions, which are generally temporary and harmless.
There are some cases where your doctor will close the area down, or order some modifications. Some of these conditions include risk for preterm labor, unexplained vaginal bleeding, cervical insufficiency or dilation, placenta previa or the presence of sexually transmitted infection. If you're not sure, raise the question with your health care provider.
Other than that, sex will operate the same as prior to your pregnancy for the most part. Some women enjoy sex more when they are pregnant. Hormones and genital engorgement that is part of pregnancy increases the sensation and sensitivity in key areas. On the other hand, some women find the additional sensitivity to be uncomfortable, and don't want those areas touched at all. It is important to communicate these changes to your partner, who won't know if you don't tell him.
Oral sex is safe, as long as you partner avoids blowing air into your vagina, and your partner has a clean bill of health himself, no HIV or herpes infections in the mouth.
Starting around the second trimester, it will be good to get out of the habit of laying flat on your back for sleep or sex. It can be uncomfortable, and cut off circulation to the uterus. During this time, some couples experiment with different positions, such as her on top or with her laying on her side. Keep the lines of communication open, be patient and have fun.
