Man and woman in bed

No one wants to talk about sex after baby...especially painful sex after baby. Moms may think they're alone in feeling pain, and be too embarrassed and confused to talk about it.

Turns out, 9 out of 10 women actually experience pain when having sex for the first time after birth. And 1/4 of women still experienced pain even at 18 months.

According to the new study, researchers in Australia gathered data from 1,200 first-time moms -- almost half the women had vaginal births while almost 30 percent had a C-section. The women were asked questions about sex at five different times, once prepartum (at 15 weeks) and four times postpartum (at 3, 6, 12, and 18 months).

Although the researched is based on Australian women, women in the U.S. (and around the world) can benefit from having a more open dialogue about painful sex, which is more common than most believe.
