A dry vagina results into bruises due to friction generated during sex. Women engaging in sex after the age of 45 years are highly advised to use lubricants during sex.

2. Vaginal yeast infection

Yeast infections are caused by a fungus called candida albicans. Candidiasis is a common term used to refer to yeast infection in women. Yeast cells multiply when the bacteria balance changes in the female vagina. The result is intense irritation and inflammation.

Yeast infection is not considered an STI (Sexually transmitted infection) even though it can be sexually transmitted. The symptoms include:

  • Vaginal itching
  • Pain during sex
  • Soreness after sex
  • Redness in the vagina
  • Rash around the vulva

A whitish cloudy discharge with or without an odor is also another common symptom of vaginal candidiasis or yeast infection.

Vaginal itching can occur when things go a little rough between the sheets with your partner. Your vagina is made of delicate soft tissue which tears easily with slightest of mishandling
