I had a baby 6 months ago, and now when me and my husband try to have sex it is very painful at first its so hard for his penis to go in, it feels like my vagina is to tight or there is something blocking it, he says that it hurts him too and feels like there is a string not letting him get all the way through... but when he does manage to get his penis all the way in its all fine,, oh and also his sperm stings very bad... im so confused!

Could be your episiomety stitching is still in tact if you had vaginal delivery and they had to cut to deliver the baby. You should have a check up to see if this is still the case and have it corrected.

You would have been given specific instructions for taking care of your perineum to promote healing.
