Broken skin refers to the type of wound or cut that is actively and profusely bleeding and requires medical intervention. A popped pimple, a small razor cut, a scratch, a paper cut........these are not risks.
You said you had scratches and red areas around your penis, but these were outside the area the condom covered...........is that correct? You also stated you had a "wound." Were ANY of these deep and bleeding heavily? If not, then you had no risk.
Perhaps in the future, if you ever have any kind of "problem" in and/or around your penis/groin area, it might be wise to forgo sex until they are fully healed.
