I would suggest cleaning yourself daily just like you did before you were locked up. This will be much easier for circumcised men since there are fewer nooks and crannies. If you notice an odor, you might request that it be allowed to be removed for cleaning. I don’t really like the look of an uncircumcised penis so I haven’t dated any guys equipped with one so I cannot really speak to this. No offense to the intact guys out there. Just a personal preference.
