Next time you're nude, take it off and strut it like you're a million bucks. Trust me, he will be sooo turned on. You will be surprised. I can't say it enough times, but confidence confidence confidence!!! It's a major turn on. Looks are important as well, but confidence is such a huge turn on. There's nothing like a girl who feels comfortable in her own skin and isn't afraid to be sexy. Force yourself next time you do get nude in front of him to be sexy, take it off, throw yourself on top of him, walk around like you're still wearing clothes. Trust me...he will be begging.
