Sex during pregnancy does help the uterus and vaginal canal to expand more so does ease the labor

For labor easily or earlier, no conclusive medical studies.

From article:
It is possible that an orgasm or sexual penetration could induce Braxton Hicks contractions late in pregnancy.
Braxton Hicks are mild contractions that some women experience towards the end of their pregnancy. However, these contractions do not indicate or induce labor so should not be a cause for concern.

Hope this clarifies Bro
