Ok so as I've said before, I'm fairly new to this feminism game. So I just wanted to reiterate that in case of offence, because I'm still learning.
When I was much younger I was of the opinion that prostitution had a valid role in society, mainly to provide an outlet for men so (a) their wives/partners didn't have to perform acts they weren't comfortable with (b) dudes that couldn't get laid had somewhere to get off so they weren't out raping random women. Yes I was incredibly young, naive, and stupid.
I do feel quite torn about the difficulties faced by people with disabilities. A dear friend of mine works providing in home care and outings for them. From what she has told me at times, they can be rather highly sexual. I'm not sure what the solution would be in this situation? Obviously the safety and dignity of all residents in a care home should be paramount and it's not certainly not the responsibility of staff to organise this type of thing.
Retirement homes are a different story - my DH Grandma was in one for several years (RIP) she was quite feisty, according to her there was great competition among the ladies for the vastly outnumbered men. I spoke with her quite a lot since her sons living far away, decided to put her close to DH and I, and as the sahm it became my responsibility to check in on her, liaise with administration. We often went as a family with the boys to join her for a Sunday lunch or weeknight dinner (residents loved seeing the kids) during those times we could actually witness some of the flirting and carrying on, all seemed quite consensual. Unfortunately seeing how poorly a lot of retirement homes treat the residents, I don't have much faith that those with abusive history are flagged and monitored. It's definitely an issue.
