Every body orifice is of use to someone sexually. Some are taboo to many, like the anus, many cultures have it a taboo to have anal sex. Another less common orifice to sexualize is the belly button. The navel can be sexy if you have a sexy figure and taut stomach, but not many of us do! Every body part there is is being sexualized by someone. In particularly large women, it can even be deep enough for a man to fuck. Now that’s not your everyday body orifice to fuck!
Most that are sexualizing the navel are into using their fingertips or tongues in it. Considering how lint can collect there and many people might not cleanse them thoroughly, I’d not be sticking my tongue in there, but to some it is a delight. A set of six pack abs on a guy is a beautiful site to see for sure, but I’ve never imagined sticking my fingers or tongue in any guys belly button.
Fashion loves to show off the belly button in recent decades with low rise jeans, cropped tops, bikinis. The sight of it turns on many men. Belly dancing has been around for centuries and shows it off in a very arousing way, with undulating hips and suggestive movements. Some love to drip things in like holding an ice cube above so the ice cold water drips in, or the opposite, the wax from a melting candle, all sorts of naughty things to do. Drip some chocolate sauce in and let your lover lick it out if they are driven wild by your navel.
