can men have any form of an std and not know it.?

Answer 1

Any/all STD's can be asymptomatic, meaning no symptoms. With most STD's people do not have symptoms.
If you are concerned about STD's you should be examined by a clinician and screened for STD's.

Answer 2

Yeah definately! A lot of stds don't show any symptoms.
The best course of action is to have a full check before you sleep with a new partner to rule out any stds. Have a look below for a brief list of common stds and their symptoms:

Candidiasis: Itching in the vaginal area, pain when urinating, and a thick odourless vaginal discharge. Candidiasis (commonly known as thrush) is not strictly categorised as a sexually transmitted disease, but it can be transmitted sexually.

Chlamydia: For women — a white vaginal discharge that resembles cottage cheese, a burning sensation when urinating, itching, painful intercourse.
For men — a clear, watery, urethral discharge.
However, often there are no symptoms.

Genital herpes: Itching, burning in the genital area, discomfort when urinating, a watery vaginal or urethral discharge, weeping, fluid-filled eruptions in the vagina or on the penis.

Genital warts: Soft, cauliflower-like growths appearing either singly or in clusters in and around the vagina, anus, penis, and/or scrotal area. There appears to be a close relationship between genital warts and cervical cancer as certain types of genital wart virus are consistently found in women with cervical cancer.

Gonorrhoea: For women — frequent and painful urination, a cloudy vaginal discharge, vaginal itching, inflammations of the pelvic area, rectal discharge, abnormal uterine bleeding.

For men — a yellowish, pus-filled urethral discharge.
Often, however, there are no symptoms, especially in women.

Pelvic Inflammatory Disease (PID): A pus-filled vaginal discharge accompanied by fever and lower abdominal pain.

Syphilis: A sore on the genitals, rash, patches of flaking tissue, fever, sore throat, sores in the mouth or anus.

Trichomoniasis: For women — vaginal itching and pain, with a foamy, greenish or yellow foul-smelling discharge.
For men — a clear urethral discharge.

Answer 3

Yes they may: HPV, HIV,...
It is possible to be an asymptomatic carrier of sexually transmitted diseases.
Depending on the STD, a person may or may not still be able to spread the infection if no signs of disease are present. For example, a person is much more likely to spread herpes infection when blisters are present (STD) than when they are absent (STI). However, a person can spread HIV infection (STI) at any time, even if he/she has not developed symptoms of AIDS (STD).

Answer 4

Yes, if you suspect you have an STD get checked and don't have unprotected sex, you can have no symptoms and still infect someone else.
