Sex Toys

So my boyfriend drunkenly ordered a prostate massager and has since been talking to his buddies in anticipation of it. It arrived yesterday and he tried it out briefly in the shower but when it came down to it and he asked me to leave our room so he could properly give it a go, I just felt awful, I told him maybe I’d at least try to turn him on a little bit and try on some new lingerie before I left, he didn’t seem to care at all and was far more fixated on his toy and for whatever reason I just had a meltdown at that point, like I literally got stress hives on my legs, he felt really bad but I feel worse because I don’t want to be jealous and insecure about this, I wish I could have just let it go, but he didn’t give me any time to process or consider how this purchase would affect me, it was set in stone because he’d already talked to his friends about it. Am I being crazy? How do I stop being crazy? Should I get my own sex toy? Anyone else had similar feelings?
