I need advice!!!πŸ˜”

So not so long ago I told my boyfriend I wanted to buy a dildo lol
He was ok with it I guess he didn't believe me 
So I went ahead and got it 
So this morning he found it in one of my drawers and he got so upset 
I don't understand why 
He says why am I hiding things from him 
But like in every other relationships I feel like it's perfectly normal and that its my choice whether to have one or not
He's very mad at me and I really don't know what to do πŸ˜”πŸ˜”πŸ˜”πŸ˜”
