How can you ease rectal trauma without taking drugs?

Use common sense: Depends on the cause, really. If sexual, use better lubrication (liberally!), if from hard stools, stool softeners, sitz baths, soothing ointments may help. Gentle wiping always a must, many otc products may be useful. If pain persists, see your doctor to evaluate for more serious problems like a fissure, thrombosis, infection, etc.
