Seduction is an art. So goes the saying. It is for this reason that at a certain point (and fortunately I would add), beauty, money and power take a back seat to make room for other characteristics of each one. Seduction is a skill that varies from person to person, but which can be improved over time.
Playing with exhibitionism is not a thing to think about too much. You will always find someone that will be more sexy than you. More beautiful, more sensual, more intense or too soft. The only thing that matters is what you do for yourself and what you want to convey. Before judging whether it is right or not to do something, you must at least try.
There are so many ways to play with your pictures. You may want to show your sinful side, as well as the erotic one. Those who decide not to show themselves, for fear of being misjudged, have already lost all their battles before even taking the field.
