There are also some creams you can get too that can help with vaginal moisture in general. @MsR mentioned a couple:
Mrs Chimp is perimenopausal/menopausal (she’s on HRT now, so it’s tough to tell ). There are a few things she’s enjoyed from here that are aimed at menopausal vulvas - she really liked the MegsMenopause Intimate Wash, and the Tracey Cox Squishy Wand is a great texture. There are quite a few other toy shapes in that squishy range too, and a few other MegsMenopause items as well.
(The search for the squishy range has some random ones in. It’s the best I could do. )
