Hi, Are you sure you are peeing after orgasm or could it be a natural 'female response'. For years some women think its an infection of incontinence but find out its really female ejaculation. You learn to use a towel on the sheet.

Its hard for your mum to see you as a woman while you are living in her house. I'm 60yrs and my 95yr old mum insists on things her way in her house. Its why we both have our own homes but I live close by if she needs me.

Move out as soon as you can.
