Well the thing is - using NSFW tag here is purely a voluntary thing that you do yourself. And if you are posting porn it is actually a wise thing to do as you will get flagged for it otherwise. But I haven't personally seen anyone flagging art with "naughty bits" for not using NSFW, and even if you do see that, that is a personal opinion on the part of the flagger and will almost certainly be outweighed by the increased support on your posting by not using the NSFW tag and allowing people to see the image thumbnail and title, etc. I am wrestling with this a little bit myself as I am about to post a song for Comedy Open Mic which has absolutely filthy naughty lyrical content and for which I strapped a dildo to my microphone. I am not going to use the NSFW tag but will include fair warning in the title and intro text that is displayed in the feed, and make sure my cover image does not include the (potentially) offensive dildo :)
Anyway - I would say personally, post away, and if you actually do run into someone flagging for this, that is the time to have the direct conversation with them and hopefully talk some sense into them. Absolutely love this selection of art.
BTW just to clarify something, I know you run a gallery - I have been assuming when looking at your posting that you have permission to post this artwork by other artists. Can you confirm that? And in that case may I humbly suggest that you note that at the bottom of your posts? You are actually probably more likely to get flagged for someone thinking you are trying to be rewarded by posting copyrighted pictures from other artists, than you are of getting flagged for posting nude art without NSFW tag.
Much love - Carl
