So I've been in a relationship for almost 7 month, and its great. But about 3 months in, I was offered the chance to 'do things' with another woman. The only reason I didn't take the opportunity is because I am in a relationship. But I've started to feel a lot more sure about my sexuality, and when someone asks me, although I say straight, I identify as bisexual. And being with my boyfriend for 3-4 month, I don't know if I should tell him, and if so how? So just drop your comments after making your choice, thanks!
