Just to get it out there: There is so much sex-negative messaging, and traumatic experiences associated with sexuality. It may not be that sex is seen as pointless, or merely time consuming, but something laden with pain and shame. If people do not enjoy or even want to be close to other people, or to hug, that's something worthy of exploration right there. Sexual acts are scary and unimaginable, and are way down the road for consideration by trauma survivors.
