HELP!! Something happens to me when I'm breastfeeding

This has got to be the weirdest situation ever. When Someone needs help, they speak up. So here it is:

"Please help! I am a nursing mother/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 sexual feelings for my own son or what is this? Please I need help!
