>>4718321dicks and pussies have to go into the "Adult Art" section of eBay which nobody looks at. eBay will remove your listings if you try to post them elsewhere, you won't get flagged or anything they'll just take them down so don't bother. Paintings of tits or butts, or man tits and man butts, can go in Paintings>Nudes which are fairly easy to sell. Also depends on the painting, I have a painting of a nude man that's fairly impressionistic that I did at a figure drawing class that is in Paintings>Nudes and they don't seem to care.
I'd recommend some landscapes and portraits too though, but when you're starting out mostly paint in the Paintings>Nudes category since it generates the most traffic. That will get people on your page to look at the other stuff.
Sex sells, but sex also sells your things that aren't sex.
