When I was a little child, I was always sick, I had a weak immunity and used to catch all the world's viruses, so I had always suppository prescription which I hated so much! all my suppositories (which were many) were forced. I always fought them with all my forces but could never excape, mainly because there were many persons involved in all the procedure to hold me and my mom to insert it.
I had to go many times to the hospital as well. I remember getting so much suppositories forced and shots! The most one I remember is when I had about 7 years and a nice young nusrse enters my room. she told me that she has to give me a suppository, I think it was a glycerin supp. Well of course my answer was No way! That nurse was so nice, so she told me that she will leave the supp next to me, and when I feel ready I can call her so she can insert it, but she has to do it. Well hours passed and I didn't call her so that nice nurse turned suddenly into a very severe one, I can't delay it anymore, she has to give it to me right now! So as I was still refusing, she asked for help, and two strong men nurses and a young nurse(i think she was a still a student) entered. They turned me on my stomach, and pulled down my panties, I was still screaming and fighting with all the energy left, but those men had strong hands and could hold me so hard. I remember that stupid nurse student standing in front of me singing with a doll trying to make me feel better during the insertion. In fact she was making me feel more nervous with her smile and dance moves with the doll. Well I can't remember anything but me creaming because I felt the suppository entering my butt. Finally they left me and I was so tired after the big battle I had to do. And then the nurse who inserted the suppository looked at me with a big smile and said "see? it doesn't hurt? You shouldn't do all this!" well in fact it hurt me but I didn't reply because I was so tired.
That was my experience! I had forced suppositories until the age of 10. then at 12 my mom suggested to start inserting them on my own, and since then, they are not scary anymore, but yet not so pleasent either.
