Your friendly neighborhood sex-toy reviewer has been telling you this for years, but now here comes the Science!: women from age 18 and up report improved sexual experiences - whether with a partner or alone - when they use lube. Interestingly, another reason for lube that I was unfamiliar with is that STDs are transmitted easier if friction causes damage to the vagina. Just typing the sentence "damage to the vagina" makes me cringe; do your friendly neighborhood vagina some good and use some lube, everybody - you can buy that shit at Wal-Mart now, and the little bottle of Astroglide lasts practically forever - go buy some now.
