Getting Back to the Friend Zone

How do you know if you are in a talking stage and how do you get back into friends' stage?

I have a problem of oversharing/finding too many commonalities between myself and the people around me, and while this has never been a problem with same-gender friendships, it definitely has been a problem with opposite-gender friendships, crossing into the dangerous territory of "are we more than just friends?"

I feel that two different people see me this way, and it feels wrong and I want to make it clear that we are just friends in a delicate manner. Advice?
