Even the most gory of movies never show the most graphic scene on the DVD cover. They leave something to mystery, plus they don't want to scare potential viewers away. A man who values an intellectual thriller is not likely to rent a movie with exposed intestine on the cover.
Keep the intrigue by saving the details until you and your dream man are intimate for the first time. Show a little chest or even a leg, but if you wouldn't show it in public don't show it online. By keeping your pics on the PG-17 or R-rated scale you're showing your suitor that you're about more than just about sex. Graphic shots may get more quantity, but it's the quality of man you're looking for.
