Do I have an infection?

Do I have an infection if my pussy is itchy?

Possibly. Get checked out.

It sounds like you might have a yeast infection. This can also be accompanied by a thick discharge, and odor. It's normal to get one, especially if you wear tight pants where air cannot easily get in. At your local drug store or grocery store you can pick up Monostat. They have about 3 different versions of it (one day, three day, seven day). I would choose the Monostat 1 because it works quickly. This comes with a small oval-shaped pill-type thing. This gets inserted into your vagina. Afterwards, try to keep your activity at a minimum so that it doesn't all leak out. The monostat also come with a small tube of vulvar cream which you put on your labia (vagina lips). This helps with the itching. You could also buy a tube of Vagisil. This works well for the itching, and it helps heal the sensitive skin. It may take a few days, but if this is a yeast infection then it will go away. If you are still having problems after using the Monostat and Vagisil, then you need to make an appointment with a Gyno. I hope this helps!

stop having sex.

You need to make sure you dry it every time you shower. Could be nothing more than it is too damp. Get a talcom powder designed for that area, they sell it at Walgreens etc.
