Yeah, I recall the early days of TS2 modelling, where erect penises for women arrived earlier than relaxed male ones. But nowadays, it should be easy to get a variety in any state. Marvine and Beosboxboy in particular do not only offer a variety of body shapes (which I personally consider more annoying than useful, having to match a skintone with a certain set of clothes, which results in gigantic menu clutter and the potential for weirdness), but also within certain shapes a variety of genital arrangements ranging from fairly normal to obscenely large. Generally, though, I prefer Crammyboy's solution, which, while also named with terms found more often in erotica, is in "non-combat" state by default, can be configured for variety and supports children as well, which is impossible using the classic body model modification, because child bodies are still unisex. Unless you are into girl penises of course.
