Is he even a guy?!

So I'm just curious about other opinions and it doesnt bother me too bad about what my finances reaction was. I asked (just kinda playing around/ but mostly hinting that I'm horny and want some) my fiance if it would be weird if I just whipped out my vibrator and went to town. We were both just paying in bed on our phones bored as shit. And he was like " uhm wtf... yeah itd be weird!" But then afterwards he was like "well I mean by all means if you want to then I guess it's ok but I can go to the other room. That's just something private. That would be like me just jacking off right here rn!"

I just thought it was kinda weird bc most guys would LOVE that.. or am I just crazy? Lol it didnt bother me much but i think I'm a little more sexually adventurous than he is maybe?? How do it get him to try new things without coming on too strong?? I'm 20 and hes 26. Is it the age gap?
