You could try nude or tease =P. Porn is hot yeah (well depending on the pic) but sometimes a character teasing the viewer is much better. For example, showing undies and bulge, the butt, the tailhole as the character looks naive or even having a naughty expression on their faces like inciting the viewer to use his imagination. You draw turtles mainly so i dont know how good they could look wearing undies or boxers, but you can use towels half hiding their parts, also objects like plushies covering the crotch or replace the erection for a soft thingy (in case it is a male).
So as you can see there are lots and lots of options you can use without drawing 2 or more characters having sex =P
