I can see that several people have commented that long nails on men is not their cup of tea - which is perfectly fair enough.
I also think that it's fair to say it's quite unusual, and to be surprised.
But equally there are some people who have reacted with disgust. I find this attitude to be quite unpleasant, frankly, and it's this kind of intolerance that discourages me from spending much time on this site. For goodness sake, you're in the business of (in most cases) making people's nails longer!
If you find such a simple thing as long nails on a man to be "revolting" - well, then i suggest you might need to look at why you feel so strongly about such a minor break with gender (and other) conventions.
