Is using a massage gun for masturbation wrong?

I’m not exactly sure as to why I prefer message guns as a vibrator sorts deal? I’ve been starting to get into masturbation recently and I’ve been struggling to find the right toy for me, I’ve found that using a massage gun and using it to tease the nub and slowly enter the core to be exhilarating and feel pleasurable? I haven’t found a good toy that suits my wants, I’ve cleaned it regularly but is it wrong? Please someone help because I’m not sure…
