I shower most days, generally after I exercise because at that point I'm covered in sweat which I think feels icky; but if I wasn't working out a lot I'd probably shower a few times a week. I do a fair bit of historical re-enacting in a location with few showers and less hot water - most people don't smell noticeably even without showering all week (I'm not sleeping with any of those people though). Twice daily showers seems a little excessive to me, I think doing so would be likely to irritate my skin although of course that depends on your skin.

I don't remove any of my hair. I think on the subject of hair removal you either need to not do it, or do it often enough that you don't have stubble which is quite uncomfortable when having sex.

I have found feminine wipes irritate my vulva. Of course this is not going to be everyone's response, but if they do irritate yours too I recommend not using them.
