Not a woman myself, but I’ve seen multiple female partners get off very intensively while using clit suckers. I’d recommend one of the cheap Satisfyer brand ones. Beware, they don’t last very long before needing spare parts or replacement. If you use them daily, they might last a year or so.

That’s not possible because of the way disk encryption works. When you unlock an encrypted drive, it does not actually decrypt it - that would take way too long and leave the disk unencrypted. Instead, the computer keeps the key in RAM and uses it to decrypt the accessed data blocks on the fly.
