Curious

So I’m bisexual. Never been with a girl, but when you know you know 😂 I’m engaged and have a daughter, and I’ve seriously been questioning my sexuality recently. I believe I’m pansexual (love anyone no matter what) but when asked I say bi. Anyways has anyone been in a situation like this? Hetero relationship then leave and get into a relationship with the same sex? I’m not going to leave my fiancé or anything I’m just genuinely curious on the subject.
