Find reason: Imo one reason for females to have abdominal, pelvic & rectal pain with sex is chronic laxity of sacroiliac joints arousing presacral nerve stimulation. Joint hypermobility syndrome and/or mechanical pelvic injury (oft multiple births) can cause joint laxity; as can hormone relaxin released during menses. Missionary position can arouse pain from pelvic torsion. Spooning might be more comfortable.

Provided original answer
During intercourse via the missionary position, the women's legs are in the trendelenberg posture. The man's superiorly stationed body weight translates through her legs, which function as levers, placing a torque on the woman's pelvic girdle. The pelvic girdle force is translated to the most flexible loci on the pelvic ring, the sacroiliac joints, which if loose are exceedingly pained due to ligament stretch.  My hypothesis includes that a woman with an unstable (subluxing) sacroiliac joint, such as I have found in many women with fibromyalgia, might be most comfortable during intercourse in the spooning position.  I do note that this hypothesis has not be subjected to a clinical trial.
