My current wife is pretty close-mouthed about her previous sex life but did confess to considering the cucumber during her single years (raising two kids). Since she's mentioned it, unprompted, a couple of times it makes me think she actually probably did. She also fantasizes about big cocks. Wouldn't be a bit surprised.
My last wife confided that in her younger days she'd often used the toilet paper spindle - she basically can't cum with being penetrated in some way. During our marriage she masturbated several times in the lavatory at her work. I can only imagine that the spindles there got involved.
