not really, I don't think any Smurf has reproductive organs so they don't get any sexual arousement. Actually Smurfette wasn't even a natural smurf she was created by Gargamel to lead the smurfs into a trap, but it misfired and she betrayed him, giving her the blond goldy locks she has now.
LOL. I love the smurfs! but yes, I do understand your concern... it is slightly suspect... :p
Lol when you think about it that way, it is. Because I know, I thought about it that way too :D haha. But just don't think about it that way, just think about it for what it is, a bunch of funny looking blue people living together :p lol
