How to wean off suction toys

I think I have conditioned myself to only be able to cum using suction toys. I’ve tried several - I have a bit of a collection - and I find myself wanting stronger and stronger stimulation to be able to cum. I’ve heard that it’s not possible to desensitize your clit, but I’m pretty sure I have…

I’d love to be able to use my hand or a regular vibrator, and especially to make it easier for my partner to make me cum.

Any pointers on how to wean off suction toys without getting frustratingly horned up b/c you can’t cum?!
