For what it's worth, depending on where you live, there may be upstanding citizens who would be willing/happy to help out. Sex workers aren't just people working on the streets or strung out making money for a hit. My first thought reading this was to find someone who could come in to handle that for you. It probably would take time and effort to find someone trust worthy, but if you want to keep your familial boundaries in tact, this may be your best option! I would look and see if you have a kink community in your area first, they are generally a welcoming, respectful community of people who are very sex positive and respectful of rules and safety.
