Hi, Im a teen male and I was masturbating and felt really horny. I decided to try masturbating anally and so I slipped my fingers in. This felt really good so I grabbed a round, slightly flat-bottomed shampoo bottle and some baby oil and lubed up. I tried to push the shampoo bottle in but I guess it was too big (1.5? inches maybe smaller in diameter) and when it did go in I felt a sharp pain like after you try and poo out a really big piece of feces and so i stopped immediately. I washed it off and then went to wipe my bum and saw a bit of bright red blood on the tissue. I wiped again and there was only a tiny bit and it has now stopped. Is this something I should be worried about? I ve heard that a litle bleeding can occur after anal masturbation/sex
