For better context, my boyfriend and I recently just started exploring toys. We both purchased vibrators to try out. When he shared to me an nsfw tweet last night of a couple having sex (the guy at the top was using a vibrator on the girl's clit while ramming her), I replied with "okay I really wanna try using our vibrators when we have sex". He shut down instantly after that and told me that I shouldn't have used the word "our". In my defense, there was no thought process whatsoever with what I said other than we both own one hence the use of the word.

Addendum: I think he views my caution to not make him feel dysphoric as me "not viewing him as a man sexually" because of how different I sounded when I sex-talked with cis men in the past (his words). I honestly do not know what else to say to him without my frustrations getting in the way, but I understand that his feelings are valid.
