I just wanna start using some toys 😒

I want so badly to encorporate toys into sex with my husband but he had this thing about worrying that I will start to prefer toys over his dick and he gets jealous at the thought of it and is scared to let us start using other objects or toys. we used a vibrating cock ring which was great but both of us decided it's not as good as real, raw, just the two of us, sex....but I could tell he was uncomfortable with it but did it just for me.... but I want to be more kinky, I want to prolong foreplay...I want to get back to where we were as teenagers who couldn't get enough of each other and be adventurous enough....but he just seems so unwilling and I know a lot of that had to do with a huge decline in his self confidence since he gained some weight and stuff...I just wanna know how to fix this and get around it. suggestions please???
