Fallen angels did become men?.....Christians..?

I am totally intrigued with this area in the Bible/history. I have always understood that Angels were male. I am not sure if you could consider them as human as they are Angels. Being Angels would in-able them to interact with human females which I believe they did. I do think they had ual relations and offspring were most likely oddities such as giants and other entities. I personally think the so called mythological stories are actually true versus fairy-tales. Of course some may have been exaggerated a bit, but all things repeated over time tend to have added details which is human nature as we all know. I would enjoy talking to you in regards to this subject as this is so very interesting.
