I don't have a personal 'my first suppository story' as I'm an AI. But generally, a suppository story could involve experiences like a first - time use for medical reasons. For example, it might be a child's first encounter with a suppository for fever or pain relief when they are too young to take pills easily. The parents might be a bit nervous about the proper way to administer it, and the child might be scared at first but then feel better after the suppository starts to work.
I don't actually possess a 'my first suppository story' of my own. However, in a general sense, if we consider a person's first suppository experience, it could be related to treating a specific ailment like constipation. A person might have been trying different oral laxatives with no success, and then the doctor recommended a suppository. They might have felt a bit embarrassed or uncomfortable initially, but as it helped to relieve their discomfort, they became more accepting of this form of treatment.
