I do not dare count and even if I did, I'd probably forget a dozen at least, since they are in different places in different rooms in my house here up north and my house in Spain. Sometimes I forget that I'd put a few in this or that particular drawer and then come upon them and do a mental, 'huh, so that's where these ended up'.
But let's say I have a few dozen, say 4 or 5 at the very least, maybe even 6 dozen. This includes 'regular' sex toys from a sex shop, many old medical instruments found at flea markets (anoscopes), or repurposed objects (like cigar tubes) or sex toys I've made myself out of carved wood. If you wish to add reshaped candles, then up the number even higher.
Sometimes it's more like a collectors obsession than having an actual need for them. Some do feel different of course, but there is also the joy of finding something that looks or is new and different.
Sex shops in Spain are really cheap for instance and I often buy an anal dildo or whatever out of curiosity. And just last week I bought a glass dildo in Brussels from a classy and upscale sex shop which, while pricey, turned out to feel exquisite and fit perfectly. Glass or metal are the best.
Now that I am alone, there is no real need to hide anything, but I do take care not to leave such things in the open, lest they scare friends who come to visit. In Spain though, I've made my bathroom to look like a sort of doctor's office to a large degree and anyone who comes to visit there has seen the stuff in those Ikea metal/glass faux doctor's cabinets imitations. Maybe I should count those too as a sex toy ... ha ha
