What objects symbolize sex?!

Things that seem inocent, but have a dirty readon behind them. Like, types of animals or foods. Something similiar to s strawberry, because strawberries eaten make oral sex taste better for the male. Also, links to these objects on a necklace would be nice. Preferablly with a diamond or two and in white gold (But now I'm just being picky). I tried looking for a strawberry necklace under $250 and couldn't find one I liked ANYWHERE!! Thanks SOOO much!!! :)
