Telling a man how sexy you think he is will really turn him on.
He will feel sexual just knowing you are thinking about him that way, not to mention that it will boost his confidence and his testosterone levels!
A good sexy picture is all about showing a little bit of skin without exposing yourself in a way that you might regret later.
A bit of cleavage and some upper thigh or lower stomach is all it takes to send a powerful message.
Men can't help but imagine what you describe, and they won't be able to stop thinking about it.
