Was the sex high risk? What are the risks in oral sex?

(1) Chlamydia, gonorrhea, and syphilis

Oral Sex (mouth to penis)

Receiving oral sex or giving it without a condom is the main way that gonorrhoea and chlamydia are transmitted according to what we see in Open House. One in every 17 men in whom we do a chlamydia test from the penis (urethra) is positive for chlamydia.

There are many cases with no symptoms, in the throat as well as in the urethra. If would like more information about the risk of catching gonorrhoea, chlamydia or syphilis in oral sex (mouth to penis) with someone who is infected, take a look at the table on the right.

Gonorrheamax 60%max 30%max 90%
Chlamydiamax 60%max 60%max 90%
Syphilismax 40%max 15%max 100%

Oral Sex (mouth to vagina or cunilingus)

Giving a woman oral sex is also a risk for gonorrhoea, chlamydia and syphilis, but is less common than mouth to penis.

Cases of syphilis have been described in women receiving cunilingus, but it is not a very likely route of transmission for gonorrhoea and chlamydia.

I would like to know more about the risks in vaginal sex

Vaginal sex is a more potent route of transmission of the viruses (hepatitis B and HIV) than oral sex, but both kinds of sex are potent routes for gonorrhoea, chlamydia and syphilis transmission.

Many of these infections exist without symptoms, especially if they are in a hidden part of the body (inside the vagina or in the cervix).

Take a look at this table which shows the risk of catching these diseases in vaginal sex with someone infected and the number of silent cases.

The risk of HIV is reduced if the sex was not prolonged, traumatic or if there was no ejaculation (less risk for the woman).

Being postive for one disease increases the risk of catching another.

Mycoplasma and ureaplasma:

These two bacterias are very infectious in vaginal sex and in fact, are only transmitted in this kind of sex (with a risk similar to that of gonorrhoea and chlamydia) but they are only considered a threat if they produce symtpoms.

Trichomonas

This parasite is an uncommon cause of vaginal infections or urethritis in men and is tramsitted only in vaginal sex.

I would like to know more about the risks in anal sex

Anal sex is the most potent route of transmission of all sexually transmitted disease, in heterosexuals and between men.

In our clinic, it is common to see patients who want to try to avoid pregnancy by practising anal sex, but they forget that it is the major way that HIV is transmitted.

As shown in the table on the right, if you have anal sex with someone infected with hepatitis B, the risk is about 100% chance of getting infected.

Similarly, (in the case of gonorrhoea, chlamydia or syphilis), the rectum can harbour these infections without any symtpoms at all.

Concerned? Come and see us and tell us what happened to you, at Open House podemos we can helpby doing the relevant tests to give you peace of mind.

Questions? Would you like to write to us?

At Open House we don't judge you, or your sexual practices. Tell us what is your concern, we are here to help you.

I would like to know more about the risks of other sexual practices

Sharing cocaine dosers

Despite sexual contacts being a minor route of transmission. Its transmission occurs because of fragile blood vessles in the nose bleeding.

I want to know more about hepatitis C

Sharing dildos

The risks of gonorrhoea, chlamydia and syphilis are similar to those seen in anal sex. In this kind of sex between women the risks are similar to those seen in vaginal sex.

I want to know more about those risks

Fisting

Fisiting in groups (in parties) without gloves has been shown to be a powerful route of transmission of all sexually transmitted diseases. It is also a high risk activity for hepatitis C and lymphgranuloma venereum. They can be prevented using fresh gloves for each sexual partner when fisting.

What is the lymphogranuloma venereum?

Inoculation of bodily fluids into finger wounds

There is no data that supports whether HIV is transmitted in finger wounds or torn nail beds when in contact with precum, semen or vaginal fluids. It is believed that the wound must be bleeding to suppose a risk.
