If you honestly have a great body then I see nothing wrong with pictures that show your assets. In a way you are lucky. The people viewing your site cannot see your personality, your abilities as a partner, or your millions of dollars should that be the case. As long as what you show is really in "good taste" and the setting of where the picture was taken is appropriate (beach, pool party, waterslide theme park, or equivalent) I would say go for it.
Sometimes a picture that is even semi revealing can be of great help. For example: Some individuals are turned off to body hair and others find it an incredible turn-on. When I was on Bear.net years ago photos were in good taste, but they showed enough fur to let others that hated excessive fur know that they were looking in the wrong place, and those who wanted fur were by the tasteful pictures informed that if you want to marry a "Wookie" look here.
Good Luck, and just be very tasteful and not trashy with your "advertising".
