you'd get more watchers... like... lots

I really wouldn't mind it. I was actually thinking about doing some NSFW pieces this summer, but they were going to be about the natural beauty of the body and not pointless orgies if you know what I'm talking about. I've seen so many pointless orgies on FA. =u=

Honestly it might be good to do that and try out different styles or techniques with how you draw. You can experiment with different things, if you don't feel comfortable with putting NSFW art on this account make a specific NSFW account for your pronz :P

The one thing you generally have to think of is you will get a very large influx of watchers, viewers and faves as the site in general leans towards NSFW material above all else, but this will also increase the likelihood that should you open for commissions, requests and art trades you will no longer be seeing SFW material outside of your own personal work, I personally fell into that pit a long time ago.

As mentioned above a separate account for NSFW material might be a good idea as it will reduce the chances, if not completely eliminate your main account from being swamped when you display adult artwork, unless you generally do not mind the idea.

I like your art, however it is Sock, so post as you like. :)

I wouldn't see it, so go for it.
Unless you don't actually want to draw NSFW and are only doing it because it's expected of you. But, ehh.

If you're really worried then you could create a separate account for the NSFW stuff. I'd watch haha
