Microbicide & Safe Sex (11)

Pubic Lice

Pubic Lice also called crab lice or "crabs," pubic lice are parasitic insects found primarily in the pubic or genital area of humans. Pubic lice infestation is found worldwide and occurs in all races, ethnic groups, and levels of society.

Pubic lice usually are found in the genital area on pubic hair; but they may occasionally be found on other coarse body hair, such as hair on the legs, armpits, mustache, beard, eyebrows, or eyelashes. Pubic lice on the eyebrows or eyelashes of children may be a sign of sexual exposure or abuse.

Pubic lice have forms: the egg (also called a nit), the nymph, and the adult.

Nit: Nits are lice eggs. They can be hard to see and are found firmly attached to the hair shaft. They are oval and usually yellow to white. Pubic lice nits take about 6-10 days to hatch.

Nymph: The nymph is an immature louse that hatches from the nit (egg). A nymph looks like an adult pubic louse but it is smaller. Pubic lice nymphs take about 2-3 weeks after hatching to mature into adults capable of reproducing. To live, a nymph must feed on blood.

Adult: The adult pubic louse resembles a miniature crab when viewed through a strong magnifying glass. Pubic lice have six legs; their two front legs are very large and look like the pincher claws of a crab. This is how they got the nickname "crabs." Pubic lice are tan to grayish-white in color. Females lay nits and are usually larger than males. To live, lice must feed on blood. If the louse falls off a person, it dies within 1-2 days.

Microbicide & Safe Sex (1)

In this first decade of the 21st century the various risks connected with having sex have (alas) increased.
The figures for HIV, chlamydia and gonorrhoea are all going up. This is almost entirely because so many people – whether they're heterosexuals or homosexuals or 'bi' – don't practise safe sex.

One way to have safer sex is to only have one partner who has no sexually transmitted infections and no other partners than you.

But, this isn't always the safest kind of safer sex. That's because most people don't know when they have infections. They are very likely to pass them on without knowing it.

Another other reason is that some people aren't as honest as they should be. In fact, about 1 out of 3 people will say they don't have an infection when they know they do, just to have sex. So most of us have to find other ways to practice safer sex.

Another way to practice safer sex is to only have sex play that has no risk — or a lower risk — of passing STDs. This means no vaginal or anal intercourse. Many of us find that great sex is about a lot more than a penis going in a vagina or anus. It is about exploring the many other ways you and your partner can turn each other on. Not only is it a way to discover new sexual pleasures, it's also safer.

Safe Sex:
- Reduces our risk of getting a sexually transmitted disease (STD)
- Using condoms and/or microbicide makes vaginal or anal intercourse safer sex
Although condoms provide the best form of protection for people who are sexually active, using a microbicide will be much safer than nothing for women for whom condom use is unlikely or impossible.

For some women and men, the contraceptive effect of condoms is a major deterrent to use; developing both contraceptive and non-contraceptive microbicides is important. Providers can counsel patients on the use of microbicides in conjunction with condoms for added protection, and as a "backup" method when condom use cannot or does not occur.

About Personal Water Based Lubricant

Lubricant is a substance, typically fluid, that is used to reduce friction during sexual activity. Water-based lubricants are specifically those fluids or gels that are made from a base of water and typically a cellulose solution. A water-based lubricant is water soluble and can therefore be fairly easily washed off. The earliest and still most prevalent forms of personal lubricants are water-based, though newer forms of oil-based and natural lubricants have come onto the market.

Because they are water-based, such lubricants can have a tendency to dry out during use. This can be remedied to some extent by applying more of the lubricant or by applying a small amount of water to the area. A water-based lubricant will dry on its own and be absorbed into the skin or dissolve after use, leaving only the residue of the other ingredients. Because a water-based lubricant can dry out it is usually best to reapply during use to prevent a buildup of friction that can cause injury such as blistering or skin irritation.
