I would imagine the adhesive from the tape would irritate your skin pretty quickly when applied, then re applied several days in a row. I heard of another post about a guy that used liquid bandage on his nipples with great success. He said it kept them at a somewhat normal state, or at least far less noticeable when he wore a shirt. Some guys couldn't get it to work, but others could. I don't know if this would have the same effect though as what you are experiencing now. Your in a tough spot, I hope this was able to help a little bit!
