When Can Sexual Activity Be Resumed After Compression Fracture Of L1?

When a woman is recovering from a compression fracture of L1 (mine resulted from a fall), how soon is it okay to be sexually active? That is, how soon is there not a serious risk that sexual activity might cause me to move in ways that could compromise the healing of my fracture. (It's been five weeks since the accident, since which I have been a back-brace most of the time during the day. A CAT-Scan yesterday morning showed that the fracture "hasn't gotten any worse," which the neurosurgeon said is goon news.) Thanks!
