Does SUCKING causes any harm?

Answer:
That would depend on what or who is sucking on what or who. Oral sex, someone sucking on someones penis? You would have to really work at it to cause any harm. It's hard to give a hickey on the penis. There is the risk of disease or tooth abrasion, but that's about it. The act of sucking in and of itself is pretty harmless.
