We've been getting a ton of sex questions on lubricant. Recently, I had a twitter exchange with a friend who never thought of including lubricant in his masturbation practice...suffice it to say he's been thanking me ever since.
"Never touch a clitoris with a dry hand" - this was the first thing Betty told me when we sat down to map out topics for our youtube series (this goes for penises too). Yes, lubricant is the #1 sex toy but I don't think most people realize it because it's so basic.
All genitals feel more sensation when they're lubed up. When you get a massage, do they rub your skin with a dry hand or do they use massage oil? Why would it be different for your genitals? Lubricant is a must have for your masturbation practice AND partner sex.
