HOODOOING A MAN'S (or Woman's) NATURE
Coercive love spells of sexual fidelity are mentioned often in the African-American conjure tradition -- so often that there is a name for the entire class of such love spells. They are called "hoodooing a man's [or woman's] nature." They come in two types:
1) Hoodooing a partner's sexual nature so that he or she is sexually faithful -- the effect is to render the victim uninterested sexually in others or, if interested, unable to complete the sex act (e.g. due to erectile dysfunction, anorgasmia, etc.). Typical love spells of this sort are the "nation sack" and a knot spell called "tying his [or her] nature." A regionally famous magic spell from Texas that accomplishes this work is called "The Blue Penis Spell" and it utilizes a blue figural candle in the form of male genitalia. (A "Blue Vulva" spell using a similar candle shaped like female genitalia is also possible, but far less common in actual practice.) If the couple breaks up and the spouse does not dispose of the nation sack or knotted string, or take off the "Blue Penis" spell, the person whose nature was hoodood will thenceforward be unable to have a normal sex life with a new partner due to the old spell in which his or her sexuality was controlled by the ex-partner. Coercive love spells like these can be taken off, however, and there are numerous ways to do so.
2) Hoodooing an ex-partner's or enemy's nature so that he or she will be sexually impotent or never be loved again -- these are spells of revenge or hostility, in other words, a jinx, crossing, or goofering spell. The symptoms may appear similar to the former type, but a sexual revenge spell is easier to take off, according to accounts by root workers. The usual counter-spell is a regular jinx-removal or uncrossing spell.
In category (1) above, there are several names and working variations. These coercive love spells have been collected in oral tradition in dozens of forms from all over the South. The purpose of them is to prevent a man from having an erection or an orgasm with another woman. They are most often called "hoodooing a man's nature" ("nature" is a euphemism for "virility"). Other names for these love spells are "measuring the man," "tying up his nature," and, in one form, "The Blue Penis spell" (so called after a blue candle burned in that version of the spell).
Here, in rough outline, is how it works:
Before going to bed with the man, the woman gets herself a length of ordinary soft white cotton string and hides it in the bedclothes. While the man is hard, she takes the measure of his penis with the string or with her finger, which measurement she transfers to the string. After they have sex, she smears some of his ejaculate on the string. (This can be done in the bed or in the bathroom.) If possible, she should not have an orgasm during the love-making that leads to this spell, because she might lose herself in pleasure and get careless, and risk being "tied" herself. She also steals a few of the man's pubic hairs or underarm hairs, or, failing that, his head hairs. (Alternatively, she should also get some ejaculate on a clean white handkerchief cloth. She should be very careful to get none of her own vaginal juices on the cloth.)
When the man falls a asleep after sex, she takes the string and ties nine knots in it (some say seven knots). The knots are made starting from the center and working outward, alternating left and right sides until the ends are reached. Each knot must be activated as follows:
She forms the knot but does not pull it tight. When it is ready, she calls the man's name and at the moment that he answers, be it with a word or a sound, she pulls the knot tight. She must then make an excuse to him, explaining why she called him. It is the difficulty of making these excuses, i believe, that has led many women to recommend making the nine (or seven) knots on separate occasions, tying one knot each time with fresh semen.
Once the string is fully knotted, some women wrap it up with the man's hairs in the semen-wetted cloth, making a packet. With or without the cloth and the hairs, the woman keeps the knot spell on her. She may put it in a red flannel mojo bag and wear the bag always, under her skirt or pinned to her panties, anywhere beneath her waist. She may piece the knotted string out with another piece of string and wear it tied around her waist. She may even thread it into a self-covered fabric belt and wear it thus amongst her clothing. When she is not wearing it, she must keep it in a locked box or trunk. The man must not see it or touch it. From then on he will be hoodood and will not be able to get hard with any other woman but her, and the only way for him to get this condition off is to undertake a lengthy uncrossing spell -- or to steal back the knotted string and untie the knots himself.
The Blue Penis Candle Spell uses a candle as an adjunct to the knot spell: The candle is carved with the man's name and a command such as "Don't get hard with anyone but me!" It is then dressed with an oil like Stay With Me or Follow Me Boy or Commanding (or all three). The knotted string is coiled around its base while it is burned in seven segments over seven days. The knot maybe burned with the candle or, as some people work it, when the candle is done, the woman puts the cord in her mojo bag as described above.
Another way to do the Blue Penis Candle Spell is to collect the semen on seven occasions as described above, and to burn one portion of the blue penis candle after each collection of semen and knot-tying, keeping the string coiled around the base of the candle when it is not required in the bed for more semen collection. In the end, there will be seven knots tied in the string and the blue penis candle will have burned in seven portions, although not necessarily on seven successive days. The string is then kept in a mojo bag, as before, or burned with the candle.
In category (2) above, if the woman gets angry at the man and wants to really do a number on him and ruin his nature, she can use the knotted thread as part of a wicked candle-burning job. She gets a Black Penis candle and warms it up, then presses the string into the softened wax the same way it went on the man. She anoints the candle with Crossing Oil and sprinkles it well with Goofer Dust (a mixture of graveyard dust, red pepper, and herbs). Then she lights both the wick and the string and lets them burn to the bottom, knotted cord and all. That is a severely coercive love spell.
As i said at the outset, there are many variations of "taking a man's measure" or "tying his nature" -- but those are a few of the best-known.
