Shaving rash (groin), surgery tomorrow

Hi i have surgery tomorrow on my groin, i shaved down this area 3 days ago, i do this often anyway and usually no issues, but there has been a heatwave here in UK and with sweating its irritating the area and caused a shaving rash - Age 40s, no others health issues (don't drink or smoke), taking no medication.

Will everything be ok surgery wise?
