An inability to sit comfortably. Rubbing or massaging of one's genital area. Frequent requests to use the bathroom facilities. The child creates drawings depecting sexual themes. This is not a good or accurate indication since television and video tapes containing explicit sexual themes are common in the home.
Children also observe their parents engaging in sexual behavior and are naturally curious.
Ask the child what the picture is about and find out if the child has included himself or herself in the drawing. Doing so can and will itself be considered child abuse. Let the professionals examine the child and stop the bleeding. If there is no sign of an immediate health risk involved, no examination is needed. Let the authorities do their jobs.
