How definitive is mansplaining?

Ladies,

I have this genuine trouble while communicating with women. If I am speaking with women of any age or profession, how do I not come across mansplaining when all along I just want to share the information with them which is part of the conversation I am having with them.

This is one thing which I am getting confused and need to learn, so that my mansplaining won't be taken as being a douche.

Thanks!
