I shave (trim) my pubic area every week with my Norelco with a clipper guard so that it stays the same length regardless of my trim schedule.
Facial hair, I have always been lucky and could go almost three weeks with out shaving as it was blond and did not grow well. Unfortunately it seems the older that I got the more often I shave and now at 41 I am shaving about once every three days, maybe four...I am so lucky in that department.
I used to shave my body hair for swim meets and wrestling and that was normally a day or two at the most before the meet.
Usually every 2 weeks I let it grow out alittle since I can just wear long pants or a jacket because I usse hair removing lotion and the chemicals aren't good and I hate the smell but Veets smells better than nairs
