Most body hair wouldn't be covered by morphs.

Most of the time it will either be on the skin textures (Most of the time when vendors have made characters with more hairy textures they have been met with a chorus of complaints about how they should have made hairless textures) or the other option is fiber mesh hair which while the idea might work in small amounts (Pubic hair for example) once you get to the point that the hair would likely include ass hair you are looking at usually pretty heavy and dense hair all over the body which can bring even the most powerful systems to a crawl dealing with likely hundreds of thousands if not millions of individual fiber mesh hairs. Unless you are just talking about hair right around the perineum and anus, if so then several of the pubic hairs have more full bush options that often cover that area as well, at least on the female side. I don't have many of the male genitals pubes so I can't say how much coverage options there are.

Though judging by the past, most often body hair covered textures, or fiber mesh body hair do not seem to be heavy sellers for the vendors that have made them, nor are they heavily used by customers judging by the images they upload.

Daz Studio now has a built in strand based hair system, so you can add hair to the body to your liking.
