ive been shaving for over 15 years so dont suffer shavers rash anymore but i ALWAYS hold the shower head as close as possible and as hot as i can stand it for a few minutes to open the pores before shaving with a good quality mans razor (womans are expensive and not as good i feel) and dont laugh i always use a little bit of Bepanthen (nappy rash cream ) to stop any irritation from my underware rubbing me sore hope this helps
