As far as new toys in reference to hygiene reasons, I have only been with three partners who used toys. Two of the partners had brand new toys, just by chance, I was not involved.. another partner was very against fluids, so there was safe sex involved and it only happened a handful of times so we were not together long enough to even have that conversation. It was a part of him, as opposed to being a "toy", so that would of been a big factor.
I talked this over with the wife, and she said she would get new toys as a show of respect. I never had to think about it before, so I can not say for 100% what my view on it would be. I think ideally I would want new toys for a hygiene/old memories reason, but would be realistic about it and realize sometimes that is just not possible - and go from there.
Someone mentioned buying a new bed.. The wife actually bought us a new bed frame once we got serious [as in coupled for two years, together every weekend, now moving in together], we got new bedding somewhere in that time frame [it was faded, change of color scheme was desired], and we just got a new mattress [old mattress be old and worn out!]
She says she got the new frame because she wanted to make new memories.. The frame had prior owners and she wanted it to be OURS.
So, we say sex toys in our case are purchased for memories/pleasure reasons as opposed to health reasons, and have been since day one. We are, what's the term, fluid bonded? Condoms are the best thing next to microwave popcorn, so those are always used too! Don't realize how important those are until you roll over in a big wet puddle on the bed from over-application of lube.. and honestly [TMI ALERT]
I don't know about y'all but I HATE lube trickling down my ass.. It takes like 100 paper towels to get it all off!
