My boyfriend likes butt stuff too much

So my partner and I have been dating for 6 months today. I jokingly told him we should buy a strap on for me to use and he almost excitedly said yes and agreed.

Now, before now, he’s always hinted at liking butt stuff. We’ve got a few butt plugs and he goes mad for those. He’s always asking for them. But now a strap on?

Am I ridiculous for worrying this is gonna go south and he’s gonna tell me in a few years that he’s leaving me for a man? 😂 does anyone else’s boyfriend enjoy butt play?
