Do you change your bed sheets each time after you have sex?

I have a throe that I have yet to use usually towels go down on the bed so I don't have to worry about the sheets. If I squirt and it soaks through the towels my partner is gladly and willingly wanting to sleep in the wet spot. If we are on the truck we try our best to keep the sheets dry unless he is going to be able to wash the sheets soon. I gave up forever ago on washing the sheets just because I came all over them
