a traumatic vaginal delivery...that has resulted in tears to the vaginal wall, or a deep tear to the perineum or an episiotomy may have an impact on how you heal and if sex is comfortable...if causing pain or problems..best to get it checked out...
ventouse & forceps are done with an episiotomy..so the way it is stitched afterwards may have an impact.....
being nervous might certainly make you more tense...don;t hurry things..the right time is when you feel ready....
it;s a sensitive topic...but if you are suffering pain with intercourse, it is worth being checked out ...
