The average diaphragm costs about 20-30 dollars, but it must first be sized and fitted by a gynecologist, so there is the cost of a doctor's fee. Must be replaced every two years to ensure correct fit and product lifespan. A tube of Gynol II costs around 11 dollars and is good for 24 doses of spermicide.
The major disadvantage to the diaphragm is that it must be used one of two ways; either it is inserted before any sort of sexual play, in which case the taste of spermicide can become an issue if the couple wishes to engage in oral sex, or is inserted after oral sex but before intercourse, which can be considered a major interruption of play and may lead to not using it all.

The female condom is a soft, loose-fitting plastic pouch made of polyurethane (not latex) that lines the vagina. It has a semi-stiff plastic ring at each end. The inner ring is used to insert the device inside the vagina and hold it in place. The outer ring partly covers the labia area and holds the condom open. The female condom is market in the United States by Wisconson Pharmaceuticals under the name Reality. In the United Kingdom and Canada it is marketed under the name Femidom. Market acceptance testing has been going on for over a year, and on August 15, 1994, Wisconson Pharmaceuticals began widespread marketing of Reality.
In theory, the polyurethane construction of the female condom makes it viable to use with oil-based lubricants, and Wisconson Pharmaceutical's hotline states that this is safe. The female condom is also the best viable alternative available for those people who are allergic to latex. The female condom should notbe used for anal sex-- the anus has no upper end and the outer ring is not enough to prevent it from being pushed into the anus and become lost.
The female condom can be inserted up to 8 hours before sex. However, most women prefer to insert it between 2 and 20 minutes prior to sexual intercourse. The condom should be removed immediately after sex.
Squeeze the inner ring with your thumb and middle finger, placing your index finger down upon the plastic inside the inner ring. Still squeezing, spread the labia apart. With your hand positioned with your palm towards you, insert the female condom into the vagina. Push the inner ring and pouch the rest of the way into the vagina until the inner ring is up past the pubic bone. The outside ring should now lie against the vulva, covering the opening of the vagina.
During intercourse, the female condom may move or shift. It should not be pushed into the vagina, and the outer ring is intended to prevent this. However, it may happen. If so, stop intercourse, fix the ring, and apply more lubricant to the penis or in the pouch.
After intercourse, the female condom should be disposed of in a trashcan. Do not flush the female condom in the toilet.
The female condom requires practice to use properly. Be prepared to take your time inserting it the first time. Those who have experience using a diaphragm will find the process familiar.
The female condom has not been tested in its efficiency to prevent disease. It is expected to be as effective as a male condom. However, the insertion process calls for two steps: inserting the ring, where the hand is outside the pouch and in contact with vaginal fluids, and then fitting the ring, where the fingers are inside the pouch, thus spreading those fluids about the pouch where the penis will go. While there are solutions to this problem (have each partner do one of these steps, wear gloves for half the process, or wash hands before the fitting stage), none of them are adequate for most people. The female condom should not be considered a viable protection for STDs in cases where the woman is suspected to have a mucosal infection such as herpes or HPV.
In the United States, Reality has been available primarily through Planned Parenthood. Wisconson Pharmaceuticals has started shipping to drug stores and it should be available throughout the U.S. in the last quarter of 1994. Reality is somewhat pricey-- three condoms and a small bottle of lubricant cost approximately $7.00 US.
Reality comes with an instruction booklet. The booklet is hilarious, mostly because of the name of the product. For example:
One thing that was apparent from reading through the descriptions was that advertising on size (or for that matter thickness or ribbing or whatever) is often misleading. A brand which is claimed to be smaller than average frequently isn't outside the normal variation. There may also be differences in size based on variations in manufacturing and these figures were probably based on single samples. Different size measurements for different styles of the same brand may indicate such variations or be an attempt to provide some size variation, in which case getting the precise style named is important. All measurements are flat and don't take into account elasticity, which might influence comfort when worn. Typical condom flat widths range from 2" to 2-1/8" (meaning two and one eighth, not two minus an eight). All the condoms listed here are both lubricated and reservoir ended. Company names are listed in parentheses. Extra words which may appear in the name on some packages are listed in square brackets. It is possible I've copied some numbers wrong (and other disclaimer noises).
