You're on visual, there is no missed approach for it, period, full stop. In the US anyway, one of the reasons ATC will ask if you have the airport "in sight" is to eliminate the IFR separation standards, of which, one is the miss. If you have to go around, you're not flying a missed approach, you are going around and the tower will have to issue a clearance of instructions.
US AIM 5-4-23 (g)
e. A visual approach is not an IAP and therefore has no missed approach segment. If a go around is necessary for any reason, aircraft operating at controlled airports will be issued an appropriate advisory/clearance/instruction by the tower. At uncontrolled airports, aircraft are expected to remain clear of clouds and complete a landing as soon as possible. If a landing cannot be accomplished, the aircraft is expected to remain clear of clouds and contact ATC as soon as possible for further clearance. Separation from other IFR aircraft will be maintained under these circumstances.
