I know a male
Shea. I think it looks VERY feminine though. I like it but I keep wanting to pronounce it Shay-a instead of
Shay.
I like
Shay and
Shae. Also Shaya/Shayha (Shay-a). I like the look of
Shea, and I actually like both pronunciations, but it's unintuitive for me to say it the same as
Shay.
Shaye is bleah, nobody needs that extra e.
Shai is very "Shy" and not very "
Shay".
