LOL, if youre serious about joining, the last thing on your mind will be your penis while youre there. You will be way too damn busy. If the rules pertaining to what you can/cant bring are anything remotely similar to Marine Corps boot camp (Former Marine here), you cant bring much more than the clothes on your back. There's no point in bringing anything besides that. Anything deemed 'contraband'....even remotely dangerous objects like jewelry, writing utensils, etc. will be confiscated, and not returned to you until you graduate. Everything you will possibly need will be issued to you. Including Hygeine stuff like toothbrush, shitpaper, etc.
