(This post veers into NC-17 territory from the usual...R/PG-13++ territory? It's by necessity for the topic at hand -- no sense beating around the bush! As I've gathered fundoshi pics from far and wide, many have featured the wearers in clear states of arousal. They're eye-catching shots despite -- or because of -- their eroticism so I've included a gallery of favorites after the main post. Merely acknowledging the fundoshi's sensuality without expressly celebrating it does a disservice to it's raw sexual potential I feel, it seems high time to strip away the cautious civility and indulge the sweatier, stickier side of fundoshi-wearing.)
It's "bound" to occur. Whether in the sensuous act of wrapping yourself in fundoshi, while wearing fundoshi, or prior to being unwrapped (by yourself or a lover); that which is enclosed within the fundoshi's folds -- namely, your penis -- is guaranteed to grow hard at some point.
"Every time I wear fundoshi, I cum," says RokushakuBouzu, one of the fundoshi-wearers I've encountered while scouring the web. He's hard merely at the thought, let alone while engaged in the action. So tying the fundoshi with an erection in mind is clearly of importance to him, and there's no doubt that the fundoshi is major fetish-fuel for lots of other people, from those who grew up wearing it to budding Japanophiles to yaoi-reading fangirls to underwear/loincloth lovers to men and women in the bondage communities.
In our society, unbidden erections can be inconvenient, or even cause for embarrassment. Even in certain African tribal systems where nudity is the norm, appearing physically aroused in public is considered tasteless, rude, and antisocial. Arousal is reserved for the private moments, the intimate encounters -- for lovemaking or the consummation of marriage rituals. In effect, it needs to be welcomed by the viewing party, or it is decidedly not welcome.
Fundoshi as a garment/undergarment continues to be a source of amazement by actually looking even better when your penis is filled with hot pulsing blood. The ease of adjustment allows you to loosen the fundoshi if you find the increasing tightness uncomfortable, or you can even slide the entire pouch to one side and let your engorged cock spring free. Quite honestly, though, the feeling of containment that an erection inside your fundoshi can bring on is one of many selling points of the sexual side of fundoshi wearing -- and as your partner unwinds you, the gradual loosening and slippage of the fabric against your sensitized parts is an aspect of foreplay to relish!
One of many advantages of the fundoshi is that your penis is enfolded in the cloth in an upward position anyway, so the stiffening of your male member within the fabric basket is visually smoothed (somewhat) and not quite as obvious underneath pants. So if you're turned on in public it isn't going to out the fact that you are also wearing an ancient Japanese loincloth. All disclaimers apply: if you're big or wearing fitted clothing, a hard on is going to be evident no matter what you do! This is not necessarily an undesirable occurrence, though -- if the environment or your company is that stimulating anyway, perhaps the moment is ripe for follow-through.
Fundoshi is a delectable accompaniment to sex. While getting undressed (or being undressed by another) is nearly always part of the fun, a fundoshi can introduce an exotic puzzle to the unfamiliar partner, certainly much more intrigue and options than underwear. In addition, a semi-untied or fully untied fundoshi can easily become an accessory to the proceedings: a blindfold, a gag, or tied around wrists, for example. One end of your fundoshi could be looped around the base of your cock, behind the balls, and the long free end can be drawn up between your buttocks, up the spine and over your shoulder, creating a cock-leash for your lover to tug while they fellate you or as you enter them. The fundoshi is also a convenient after-sex wrap, when a loosely tied loincloth might be just the thing to accompany glow-y post-coital lounging. Or, in a purely utilitarian sense, it can be used to wipe up splashes and dribbles!
Another fun way to use a fundoshi during sex (or masturbation) is to tie it on with a small vibrator enclosed in the wrappings, just behind the root of your cock where it will stimulate your prostate and perineum. The architecture of the fundoshi causes the vibrations to travel through the entire garment, and vibrations on the perineum often result in extremely pleasurable sensations, not to mention copious amounts of clear pre-cum liquid. Try touching a vibrator to various parts of the fundoshi, it can be quite surprising how the garment amplifies and transmits your sensations.
And partners, as fun as it is to free your lover's cock -- It's OK to leave the fundoshi on for extended foreplay, to nibble and tease, to stroke, caress, and fondle your partner through the cloth, or to grab and pull on the fundoshi (always gently at first -- keeping the lines of communication open!). Your fumblings with the snugly wound fabric are probably not minded at all -- they can be an additional turn on. Don't be afraid to make the fundoshi a big part of your lovemaking session. Ask to be wrapped up by your lover -- one of the most fun ways to wear a fundoshi is when it is wrapped around your body by another person! It's fun and educational. Or ask to be tied up, etc., with it. Nearly every sex toy and accessory pales next to the versatility of this simple length of cloth. But that doesn't mean fundoshi doesn't mix well with ropes, vibrators, fleshlights, butt plugs, cockrings, you name it.
In truth, there's no real necessity to take the fundoshi off at all! Just as you can don fundoshi after you've pulled your pants on, you can leave your fundoshi tied during your sexual linkages -- just slide the front pocket to one side along the waistband so that your balls and shaft are free. Many men enjoy the sensation of the twisted thong portion against their anus as they thrust their hips, and partners have something to grab onto if things get wilder.
On top of that, not much is easier to launder than a fundoshi!
