Iyanya's 'Explicit' Birthday Cakes

Today is the singer's birthday and his twitter and instagram pages have been 'buzzing' of love messages sent to him from his fans. The first cake above was presented to Iyanya by his manager, Ubi Franklin and his other team members. Good cake! But are they saying what Iyanya is known for is S*X? S*x and s*x and just s*x?
