How to get over my OCD of taking showers?

i take up to 4 or 5 showers a day but it is mostly 3. one in morning evening and night and if i feel dirty right after the shower i freak out and take another one. i cant stand knowing people or being around people who take one shower a day i feel sadness for them. showering is my life i don't think i can last one day without showering or else i cry and freak out. i don't ocd with germs i don't obsessively wash my hands i dont mind it i dont clean objects 24/7/ its just with showering. if i dont take showers i feel dirty but people say im not dirty i dont sweat or smell. can someone give me advice or help?
