Caught Myself Masturbating at Work

I never thought I'd be one of those people, but last week, I did it. I was in my office, alone for a few hours, and the stress just got to me. Next thing I know, I had my hand down my pants, rubbing against myself under my scrubs. It felt so wrong, yet there was this primal need that overcame any sense of professionalism or shame. My fingers moved fast, slicking between my folds until I felt the pressure build and then explode into a wave of release. I couldn't believe it, how far gone can one be? Is this just work stress, or am I slipping in ways I don’t want to admit? Should I talk to someone about this? Am I losing control?
