Do these areas ever tan up to the point where one does not have to worry so much about sun burn?Please & thank you.
It really depends on your skin type. If you have areas that can tan up enough not to have to worry about burning anymore, then those other areas will as well, once they can start getting sun on them. Then there are others who are fair skinned enough that they always burn on the more commonly exposed areas, so they will also burn on those other areas you are asking about.
So, yes you will need to put sun tan lotion all over everything until you get to the point of not burning anymore. Especially those places that may have not seen any or not much sun.
Speaking only for myself....I tan everywhere and after a while, you don't have to worry about getting burned. That is not to say that you don't have to use sunscreen, however you won't have to be worried about getting burned. Once tanned, I can spend a week at a nude beach and not have to worry about burning with no sunscreen except that I always put sunscreen on my tattoos to protect them...I don't let the skin around them tan.
One more thing.....for me anyway.....it you want an all over tan, you gotta make sure to....uhhh....hummm.....get the wrinkles out.....or you'll have a funny looking tan.
Newbie here too -- went to my first public beach last week - first time outside naked in the day time (very often at night however).... Was only there for about 1.5 hours, didn't put sunscreen on because I normally don't need it for that short of a time. My chest, back, legs etc are fine... my ass however is still glowing bright red. You can see it from the space station probably -- so I would definitely put sunscreen on - everywhere! I was a little worried about other more sensitive areas so I put sunscreen on and no issues... but everywhere my trunks would normally be that didn't have sunscreen got cooked.
