Lonely Night Shift Desires

I'm married but work nights and am home alone most of the time. Tonight, after a long shift, I met a stranger online and we had rough phone sex with no holds barred. His voice sent shivers down my spine as he guided me to rub my clit hard, pulling on my nipples until they hurt, all while moaning into the receiver about how wet he was getting. Afterwards, feeling dirty and satisfied but also so empty, I couldn't sleep. Does anyone else relate? Is this normal?
