I'm sorry that no one has experienced this. I had radiation for rectal cancer so it was targeted in the same general area. Your treatment center should advise you about how to protect your skin - my treatment center recommended Aquaphor.
I'm not sure if the radiation will cause diarrhea or not, but be prepared just in case. They told me to take Imodium.
Lastly, you might experience vaginal stenosis - shortening of the vagina. Ask about that if they don't talk to you about it. Most centers recommend using a dilator, usually after treatment. Best wishes.
