Question

In flip effect monsters does its effect works only during my turn or every turn?

Answer 1

When the monster is flipped it's effect is activated the turn does not matter even if it is yours of your opponent's.

Answer 2

a flip effect monster, funnily enough, means it's effect works ONLY when it is flipped, and it can be used in either players turn (unless the card says otherwise)
