My flatmate heard me masturbate. I think he did, and I feel cheap and disrespectful. I sleep inside a mosquito tent, so I was aware that the window was open and he, sitting downstairs on the balcony, might hear, but I was too tired and too turned on to pause and go close the window. I was quiet, very quiet, but I know one hears everything in this house, and I think he could definitely hear me breathing heavily, turning on the bed, making small sounds. And I hate myself for it. I hate myself for knowing it and still allowing myself to go on, for not practicing more self-control. He is so respectful towards me. I've been living here only a month and a half. He is fifteen years older. When his girlfriend comes over he is super discrete and respectful. This was wrong, wrong, wrong, and just plain cheap. I don't want him to see me differently. I hate myself and regret this to tears.
