I am atracted to ladies but have a boyfriend.iwant to know what should i do. i even fantasise about ladies?

Well, you're already in a relationship so unless its open that means hands off to both es. But hey, when you're free go out and date a chick. Get a girlfriend...see how is goes. As far as now, you gotta decide if you're really attracted to chicks thus meaning you might be bi or if this is just a phase of some sort. But you'll never really know until you put it to some kind of test
