Does placing underwear that may be contaminated with madhy next to the bed during intercourse cause the ground to become impure, and how is madhy purified if it dries on the ground or bedding?

If the clothing soiled with madhiy (prostatic fluid) is wet and its contact with the bed is certain, then the point of contact becomes impure (najis). However, if the madhiy is dry, or the clothing is not soiled with it, the bed does not become impure by contact if it (the bed) is dry. If madhiy soils the bedding or the ground, the soiled area must be washed because madhiy is impure. The ground is purified by pouring water over the impurity until its color and smell are removed, or by drying, according to some scholars. The impure bedding or ground must be purified if a person intends to pray in that spot.
