My partner and I use toys, no shame there as lesbians! But maybe only half of the time, possibly even less. Toys can get distracting- changing functions on vibes or batteries dying, having to stop and put on a harness, etc. But they also can be a lot of fun and add variety to things and I personally am a big fan of both wearing a strap on and when my partner uses one on me. Being disabled toys can help when my energy is low but then holding and using a heavier toy or one that requires my arm/hand be in an u usual position can also be painful. She uses toys more than me because if I'm not well enough I'm an awesome dirty talker and help that way.
With all of that said there's something so good, so intimate and hot about feeling her body with my mouth and hands, feeling her orgasm while my fingers are inside of her. And sex toys just do not and will never have the same feel or the warmth of her hands or mouth on me.
I've definitely heard of lesbians who don't use toys but I'm pretty sure they're in minority. If anything I would guess lesbians often have far bigger collections than straight couples! And I think some women, believe it or not, are still not aware of their options- not all sex toys are penetrative, not all look like male genitalia and by extension not all sex shops are anti women or unfriendly to lesbians, etc. (those are some of the reasons some lesbians refuse toys).
