Okay, this is not about a penis, but about my anus/rectum... I did something incredibly stupid, I admit. I thought it would feel good to experiment with water jetting into my anus. I have an old Waterpik that is not used anymore for oral care, so I thought I'd try inserting the water jet into my anus. Big mistake. My had hit the pressure control on the handle and shot the water pressure up to full pressure. I turned it off immediately, but before I could turn it off, the strong water pressure caused a very sharp pain to the inside of my anus, probably about 2 inches inside. There was minimal blood when I expelled the water, nothing to indicate that I was bleeding to death or anything. Now, there is a very dull feeling of discomfort in that area. When I insert my finger, I can feel a small lump about the size of a pea about an inch to an inch and a half inside my anus. Have I don't some real damage? I'm 22 years old, and do not suffer from hemorrhoids or any other problems in that area. Please advise if this will be okay. I really don't want to go to the doctor with this incredibly embarrassing problem!
