I Get Séxual Feelings Whenever My Son Sucks By Bréast ––Mother Opens Up

This is strange, and she decided to open up about her situation because she needs help. Her cry below...

I am a nursing mother and wife. I get wet and sometime cum when I'm breastfeeding my 7 months old son who happens to be my first baby. When he suckles my breast... gosh! 

What is happening to me? Are there other mothers out there who have had similar feelings? What can I do to stop this? Am I developing unhealthy séxual feelings for my own son or what is this? Please I need help!
