When you accidentally put an adhesive tape on a fresh wound, you will feel pain when pulling it out and blood could even ooze from it again. If the tape is not clean then the wound could be infected from the given bacteria depending on the framed area. You need to see a doctor for wound dressing.
Dude, considering the area you put this on. Call A doctor, go in!!!!!!!! It's making me buckle over just thinking about it. Before you make it worse, SEEK PROFESSIONAL HELP! i know it's embarrassing, you have to though!!! Good Luck.
