is this wrong ?

so my boyfriend and i have been together a little over a year and a half- and don’t get me wrong, what we do is great, but i’ve been wanting to spice things up for a good while now and every time i bring something of the sort up, he says he’s interested but then it’s brushed under the carpet. i’ve talked about handcuffs, getting a vibrator, whips, blindfolds, etc. and he just doesn’t seem to have any interest after we talk about it. so recently i got myself a dildo and a vibrator and i can’t bring myself to tell him. when i went to get it i told him i was looking for something at the mall for my mom (which i was but yknow) so if i just randomly bring it out he’d be like where in the fuck did that come from or if i act like i haven’t gotten it already and say i’m gonna go get one i’m afraid he’ll be like “why would you do that?” and then i’ll feel stupid for wanting to use one with him. GOD this is so complicated someone please help i just wanna have a good orgasm and it’s all difficult now
