What exactly are you cleaning up? Orgasms don't usually cause a huge rush of fluids (except in men) that would necessitate a cleanup. Do you think it could be urine?
What you are releasing is a form of female ejeculate, and I think you will find that it is quite common, but you girls dont like to talk about it, you've not said where these are happening, on a bus in a car, or in your seat at school, college or work.
You need to control your urges more, and try to wait till you get home then enjoy them there, more private.
Good Luck
