ok maybe it’s a retard question but hepefully you won’t make fun of me 'cuz i really need to know this.
So while you’re taking a shower (and obviously are naked) is it ok do wadu in that condition? or are we always supposed to be dressed up while doing a wadu. i’m asking this because of the fact that we have so say some ayats and it might be a disrespect.
u shower naked 
do u while dressed up!
actually u r required to make wudu for a farz ghusal.....n its mustahab (advised)to do it for normal ghusal.....!!!
last i checked, yes and probably the rest of the people around the world too…who take shower that is.
first you take ghusal then you do wazu....i dont think u can do wazu and ghusal all at once
the scholars say when you take a bath , the only thing you need to do is wash your mouth and clean your nose, both three times and that's wazoo
ps: don't look at yourself( ie: private parts)
Good question. I've been wondering this for a while also. Some people have even told me that after you take a shower, wazoo is not required. I don't think that's true though, but I did always wonder if it was ok to do wazoo in the shower while being naked.
its ok as long as you dont sing.

then like how would you clean your thighs/knees?
assalamoalikum 
this is true as the parts of the body which need to be washed for a valid wuzu are washed/cleaned even though one might not have niyaat to do wuzu, its true!!!

Lets not confuse wudu with namaaz. Wudu and ghusl are cleansing processes while namaaz is worshipping. You do not need to do after a full ghusl shower. Think about it, how else are you going to properly clean yourself if you aren't in the nude.
After you are done with your bath and cleaned your thighs and private parts, rinse your mouth three times and nose three times…THEN don’t look at your privates…Don’t tell me you can’t wear a shalwar without looking…
oh after the bath…i thought we were not supposed to look while we were taking a shower..
True, if we are doing Ghusal, then we don’t need to do extra complete wuzoo, as its a part of Ghusal,
As lajawab mentioned, do it …and also put water after mouth and nose, to whole body for three times,
Just remember before doing Ghusal you must make a niyya’t for Ghusal, and after Ghusal there is a dua, if you don’t know then just recite first and second Kalmaa!
I do Ghusal when ever I take shower, so I am in like in wuzoo till it break!
Take the Ghusal or wuzoo so seriously, and try to be in Wuzoo all the time, as it protect from doing bad deeds, and socondly if we die, we must be in the form of Wuzoo 
Go here and read Chapter 8 and 11, it explains how to do both wudoo and ghusl.
