People always referred sex as a "private" thing. What's so wrong with being opened with something that brings both pleasure and joy to both body and mind? Serena and everyone of her kind were open to this yet they were also privy to keeping their identity from humans. Serena didn't see the problem of keeping what she is from anyone. When the elders of her kind discovered this, they were dead set on eliminating the problem. The last thing they need on their list of problems is a rebel.
Serena always felt like an odd ball when around her kind. They had "rules" to follow, were deadset on reproducing and keeping themselves as privy from the human eye as possible. They never heard of enjoying life? Thus reason why she decided to become a loner. Well, one of the reasons. She never felt like she was really one of them, she always felt different. The elders always preached about being one big family and how they would have to look out for one another but can never live up to their word.
That, she learned the hard way.
