I think it’s important when sketching to practice both male and female models. I also like to get variety is body type, age, ethnicity, basically give me lots of different stuff to draw. Sometimes I’m not sure what’s going on in terms of placement of torso or limbs when I start but that’s what the sketching stage is for – figuring things out. It’s really nice working digitally when you’re drawing a leg too long and can scale the whole body down or move it over. Also, I have no qualms about drawing nipples or genitalia, I’m just ignoring them because they’re not relevant to what I’m trying to get out of these studies. Maybe if they’re longer drawings with shading, I don’t know. The whole NSFW issue is never relevant to me when browsing but I imagine people viewing my site care about it. Not that I’m drawing anything particularly explicit but some people are up tight about even artistic nudity.
