DAE get the sudden urge to clean themselves more thoroughly/harshly?

I hate bathing (ASD) but I do it every day because it is Required and Expected. Most of the time I get in and do what I need to and get out, but occasionally I get this urge to be really thorough and scrub really hard with the rough sponge. Does anyone else get these random urges? I don't have OCD as far as I know and it doesn't happen often.
