My collection surpassed any possiblity of being stored discreetly in my house a long time ago. I generally try to keep everything upstairs, just out of respect for people who find that sort of thing embarassing, and I only let them go upstairs after issuing a warning that something you see can't be unseen. The giant sex swing and stand also made hiding stuff difficult, but I don't have kids, and my friends know me well enough not to be surprised. And I'm definitely not shy about it; I'm happy to show my collection when people ask, and I've had many people ask me to be their escort to their first adult store.
It can be easy to get put off toys if you buy cheap crap that falls apart; it's even easier if you buy an expensive piece of crap. I'm confident of my knowledge of the products and think I can make informed recommendations. The employees are usually pretty shocked when they realize I know the products much better than they do, and own a good portion of the store's better-quality inventory.
Also, back at home, the new trend toward rechargeable toys has made life difficult, because I'm having to resort to charging them using power strips, which usually leads to a tangled mess of charging wires.
