So, uh, here in Australia we have a disability insurance payment system (NDIS). There was some hubbub recently (last year, I think) where the government wanted to stop disabled people from using NDIS funds on prostitutes. The argument against was that a lot of disabled people lack any sort of affection in their life, therapists don't touch or cuddle you, and so sex workers could make up whatever difference.

I don't really remember where those discussions went. It's not that sex is a "need" in the same way as oxygen or food is, but I think people do "need" an amount of affection in their life, or social connection.
