Dear Jacky

If you are able to retract foreskin when your penis is erect, then chances of frenulum being significantly "tight" are little. But to loosen it further and to keep the area clean, you may regularly retract it, while bathing and use a little bland soap (like "baby soap") and water to clean it.
