When the solid has a high affinity for water - in which case it is called hydrophilic (high energy e.g. glass)- water spreads. In the opposite case of hydrophobic (low energy e.g. teflon) surfaces, water does not spread but, instead, forms at equilibrium a spherical cap resting on the substrate with a 'contact angle'.
Infections such as trichomoniasis, gonorrhea, and Chlamydia (all STDs); and yeast infection can all cause vaginal discharge. Vaginal discharge can be associated with other symptoms such as burning or itching. Antibiotics are given for infections that cause vaginal discharge.
When symptoms appear, people often suffer from abnormal vaginal discharge and vaginal bleeding, discharge from the tip of the penis and pain when peeing or during sex. When left untreated, chlamydia can lead to infertility in women and men. When youâre infected with chlamydia, other STDs may also be present.hen symptoms appear, people often suffer from abnormal vaginal discharge and vaginal bleeding, discharge from the tip of the penis and pain when peeing or during sex.
