Oddball neighbour

I have been emailed by a neighbours husband in a weird way the email came from his email address not hers but obviously he got my email address from her. I actually don’t know what to do about this now I saw them both together last week and it’s gone from “that nice couple” to wtf mind games does she know he sent that random massage offer?
I now feel really uncomfortable but on the surface it was same as before nice smiley neighbour couple, come in anytime, come and sit down only I don’t really want to be alone with him… I’m just out of hospital and quite frail I don’t need this , I tried to pretend I hadn’t seen them but he saw me stagger past and called me over – they only live 15 metres away and he’s offering massages? Just odd and creepy.
He’s not a masseuse. It seemed really inappropriate. Maybe I’m paranoid as I’ve been sexually assaulted in past and also had problems with inappropriate and random post op. massage offers that escalate before – it seems to be a thing with healthy men on sick women.
I showed a friend and she totally thought it was a come on. So it wasn’t just me.
Here we go again, do I ask the wife if she knows he offered whilst telling me he wasn’t any good at massage but wanted to practise?
Please guys stop doing this! Use some sensitivity. If I wanted a massage I’d get the district nurse in or my mum.
I went into polite mode and he was just smiling at me while she chatted so I think she doesn’t know and part of me thinks it’s a kinky power trip. And yet honestly he seems friendly and ok too, so maybe he’s just clumsy and clueless. Don’t want to cause trouble for this couple or jump in blaming anyone. I just don’t know whether to mention it again and I’ve tired of having to work this stuff out….
I’m sure some healthy men might get similar odd offers from married women but you can be a lot more assertive when you are well… it does seem to be sick women getting them from healthy men when we can’t exactly run far or fast..,,
Is this sexism ? Do sick men get this?
I know which gender is most likely to perpetrate sexual assault and really that should be a factor to think about before you send an email offering your amateur physical services to your neighbour.
If I wanted medical massage he knows full well I could get it off my mum. It must be a come on. How odd. How creepy. Does she know and do I say? If I mention it to my mum I know she’ll just say it’s not a thing and not cause a fuss.
Feel a bit less safe, thanks
