Late Night Fantasy Fulfilled

I've been married to the military life for six years now, and I've got a confession. Last night, after putting the kids to bed and spending a few hours working on the computer, I found myself alone in our spare room while my husband was away on another deployment. It had been months since we'd last seen each other, and I decided to indulge an old fantasy of mine. I stripped down completely, laid out some silk sheets from my secret drawer, and played a series of recorded messages from my husband that I've saved for just such occasions. I started touching myself as I listened to his voice, feeling the pressure build up inside me. Soon enough, I was straddling an inflatable dildo designed to look like him in every detail, the way he liked it rough and fast but with control, and I let out a long moan as I began to ride it hard. My hands explored my body freely, gripping myself tightly, feeling the slickness between my legs grow more intense with each thrust. By the end of the session, I was covered in sweat, panting heavily. Afterwards, I felt both relieved and slightly uneasy about how satisfying that fantasy had been for me. Is it normal to crave this kind of alone-time pleasure when your partner is gone? Do others find it as cathartic? It's not something I can bring up with my friends or family, so I'm reaching out here in hopes someone else has some insight.
