Thanks for the query.
The possible causes for your pain are:
-Disparity between the genital organs leading to excessive stretching, post-coital tears etc.
-Possibility of adhesions due to previous surgeries.
-Recurrence of endometriosis
-Psychological fear etc.
So you try to use some lubricant analgesic
jelly during intercourse and change the position of intercourse.
Possibly these can help.
If the pain persist once go for repeat examination and ultrasound
to find out the possible factor and get treated accordingly.
