If some1 has shingles(a form of virus) can this also show up as genital later?

My long time lover has had shingles in the past and knowing that this is a form of the virus(coming originally from chicken pox). If the immune system has been depleted from stress, depression and recent radiation treatment to the testicular area-is it possible to later have what appears to be pimple like substance -the same as what looks like genital ?? Confused and in need of help. Thanks.
