There is a tendency for people - no doubt including a number of doctors wishing to justify their own unfortunate condition - to glorify the circumcised state and claim that there are "hygiene" benefits to having a dry penis, less "infections" and such. And to a very minor extent, that may be true, though of course, it makes much more
sense to take more definite measures to avoid such infections, particularly the sexually-transmitted ones (STDs).
One variant of these "enthusiasts" are those who enjoy the appearance
and supposed "benefits" of being circumcised, by a practice of keeping their foreskin permanently retracted - it is possible with due persistence.
To the contrary, it can be pointed out that the underneath of the foreskin and glans is essentially mucous membrane - like the inside of the mouth and of course, the corresponding area within a woman's vulva - which is entirely adapted for remaining moist and indeed, is actually "washed" by the urine (and other secretions) which as it comes out, is in fact perfectly clean and sterile under normal circumstances.
If you read far enough through my contributions (here and elsewhere), you will note that I generally recommend the practice of retraction of the foreskin to urinate, teaching this to young boys as soon as they are able to do it themselves, and point out that this frequency of retraction will in itself, even without great attempts at wiping and drying, tend to clear the accumulation of smegma sometimes noted at puberty (though in fact, the practice of masturbation will no doubt be even more effective).
Speaking of smegma, an excess appearance of this is quite likely due to excessively
zealous attempts at "cleaning", particularly using soap or even worse, "disinfectants" which greatly irritate
and inflame the mucous membrane and cause it to grow and shed (desquamate
So, whilst I may suggest that frequent "airing" of the glans may have its advantages, I would not say that further attempts to "dry" it, or "treat" it in any specific way, are at all appropriate.
