Need Your Advise (Relationship)

According to the post on Nailalez   by a lady known as Dupsy .

 Hi am dupsy007 and I recently joined this forum.been following it for a long time,and God knows I love the sex stories,and that was why I signed up.
The reason for writing this is to get other girls opinion about if its wise for a bisexual Nigerian girl to let her boyfriend know her sexual orientation? And if he is aware, is it wise to let him know your girlfriend or know the girls you having sex with.cause I am in this situation right now.my boyfriend is aware I am into girls,and he says he's cool with it.he's good at keeping secrets, but I don't know if it would remain the same say we breakup.
