The question about sex toys...

Ok so i just got out of a 4 year long relationship and at one point this girl use to work in a sex store.
now that we have broken up and now i have a plethora of kinky shit left over. Some of them were expensive as hell (there was this multifunction vibrator with rabbit that was 50$).
Do i need to get rid all these things or can i use them with new partners.
I don't want to sound cheap but if i liked using some of this stuff do i really need to by a new one for new partners?
Just want to get some opinions on the matter
