I wouldn't even waste enough energy thinking about sexcoin to be skeptical.  It's a shit coin that nobody uses and never will.  If I'm not mistaken I've seen it on yobit being given away as a free coin, which ought to tell you in what high regard the market thinks of it. 

Whatever 'the sex industry' is, it doesn't need its own cryptocurrency.  And if people need to use crypto to buy sexual...whatever...bitcoin would work just fine for purchases.  There is absolutely no need for coins to be developed for every industry that exists.  If I were Op I would avoid sexcoin and never look back.
