Becoming excited when talking to girls

Q: I am 22 years old and work in an IT company. I have to interact with a lot of girls all the time to solve their computer issues and while talking to them I get excited and a white liquid flows from my penis. But, it does not lead to ejaculation. Altough my intentions are not pervert I had this issue when I used to carry small kids as well but it has stopped now. But I still have this issue with girls.So,does it break my gusul ? Do I have to take gusul again? Is there any way to stop this?
