A Military Caregiver's Secret Pleasure

I've always taken care of my husband in everything. When he's away on deployment, I indulge in a unique form of pleasure, reverting to a submissive role at home where I'm cared for by him through phone calls and messages. It helps me cope with the loneliness and provides a sense of emotional connection that sustains me until his return. But lately, I've been wondering if this is normal or if there's something unhealthy about it. Anyone else ever experience this? What do you think?
