That's fine. I have heard that from people before.
However, in their/my defense:
Vivian was a boy's name before it was a girl's name. Vyvyan is how
Oscar Wilde's son's name was spelled and I just like it for great and terrible reasons I can't explain.
Shealyn has been on my boys' list for a decade now. I have known two male Shealyns and one male Shayley in my life (and a handful of Sheas.) It's masculine enough for me. I'm not into to "macho" sounds anyway.
