Intercourse - Impact On Vagina

The vagina is a muscular, tubular structure of the female genital tract extending from the vulva to the cervix (the opening of the urethra). Sexual activity affects vaginal health in a number of different ways during intercourse and in the long term.

A few of the varying effects and the factors responsible for these effects are listed below:

1. Changing size of the vagina: The vagina is designed to be elastic and adjustable. So, no permanent change in size is possible but it does undergo temporary changes in sizes as effects of sex. The inner walls of the vagina enlarge during sexual intercourse and during childbirth. Tissues in the clitoris puff out and harden, this also causes an expansion in size. It takes a while to get back to its normal size.
2. Vaginal secretion: When you are aroused during sex, the blood vessels supplying the vagina expand immediately. The blood flow increases to lubricate the vaginal walls (rugae). The rugae unfold and the space increases. These secretions are important because, women who are sexually inactive for a long time at a stretch, experience dryness that leads to urinating difficulties and rashes.
    
3. Unusual discharge: Apart from natural lubricants, vagina secretes some fluids, the process being termed as 'female ejaculation'. A tiny amount of white fluid made of prostate plasma cells, is produced just before you climax and discharged with some quantity of urine. Sometimes, prostatic specific antigen (PSA) and prostatic acid phosphatase (usually found in semen) are also found in the secretion.
   
    
4. Infections in the urinary tract: The friction caused by sexual intercourse may cause small cuts which enable bacteria to pass from the vagina to the urinary bladder through the urethra. This causes infection in the bladder, the urinary tract and the vagina. These can be avoided by using a condom or by urinating before and after having sex.
5. Vaginal pain: A lot of women report the experience of pain and discomfort inside or around the vagina during and immediately after sex. The pain can result from repeated sex within a short period of time or reduced secretion of natural lubricants. If the pain is too severe, you should see a doctor because yeast infections or chronic vulvodynia can also be responsible for the pain sensation. If you wish to discuss any specific problem, you can consult a gynaecologist.
