The reason I asked about your period was that the clitoris can get shrunk only if the level of estrogen decreases in the body, as in menopause. But since you have regular periods, that can be ruled out.
I suspect that more than the clitoris having shrunk, it is likely that the hood of the clitoris is slightly inflamed and hanging over the clitoris so that the clitoris appears shrunk. This does happen occasionally, especially if you have a vaginal infection of some sort. A vaginal infection will also decrease sensitivity and will affect orgasm.
You need to take the following steps to decrease the inflammation:
- Take a warm hip bath. This means that you need to get a large bowl, large enough for you to sit in. Half fill it with warm water and add 3 capfulls of Betadine solution (available OTC). Sit in this solution 2 times a day.
- Apply Neosporin or Bacitracin ointment over the area twice a day..
- Use Monistat 7 tablets as well as gel to cure any superadded fungal infection.
- Take Motrin 500mg (OTC) twice daily after food for 5 days to decrease any inflammation and infection in the vagina
If the infection is mild, these steps may cause the inflammation to subside. But if there is no improvement in 7 days, please see your doctor.
I hope this helps.
