Can we just talk about NIPPLES for a minute?

Alright, as strange as this sounds, one of the big challenges I've had doing this type of art . . . is nipples. I can't seem to find a . . . nipple style, if you can call it that. Some of the ones I do feel a little too realistic, and when I try to go cartoonier they also look odd. I'm not really sure . . . Maybe I just need to DRAW LOTS OF NIPPLES til I figure it out.

But I was hoping the handful of people who read this journal might be able to help me out here. So I'm posing this question to you:

What kind of nipples do you like the most in this type of art? And out of the nipples I've done, are there any you particularly liked?

Link me examples if you want; I'll take a look. I'd really like to get this figured out, since obviously drawing nipples is kiiiiiind of important with what I'm doing here and it's getting frustrating to me.

Hope everyone's doing well! I owe a few people some notes; you'll have to forgive my lack of correspondence lately - when I'm not drawing I'm working on stuff for my other shop.
