First....if you spend too much time being "girly girly" he is gonna think you are nuts. Camping is for getting back to "nature". Find out what kind of camping you will be doing....
Tent Camping
RV Camping
Facility Camping
It sure makes a difference....remember one person's concept of camping is another person's idea of "hotels without room service"
Things to remember when camping...
A "spit" bath can do wonders for keeping odors at bay. Unscented biodegradable soap and a pan of warmed water with a good washcloth is pretty much all you need. Soap, wash, rinse, rinse again.
Clean clothes daily. I know this seems silly to say...but CHANGE EVERYTHING! Use deodorant/antiperspirant (again unscented is more desirable). If necessary, changing shirts during the day can help.
Keeping properly hydrated will help as well...
