but yeah I mean I had a friend (girl) she called me like at 11 PM shes like "Dude we were making out and now this guy got into the shower. .. WTF im left here all alone in his bed"
...
still. . .the shower is a mood killer before sex. . .unless you get in togheter 
Well... duh!
It's a mood killer if you are in the middle of it. I hope Proin is referring to taking a shower before actually meeting with the girl. Say, she is expected by 21:00, you take your shower at 20:00.
This is mostly necessary if you are expecting lotsa foreplay, because tongue is involved, and nobody wants to taste each other's greasy body. Otherwise, if you are going for the prize in a 5-min race, say, to... actually conceive a baby, it doesn't matter.
if you were referring to my post about lime and shower. . .yes it works like wonders. . .hasnt failed me once!
*offcourse I think it goes without saying that you must sleep with your sheets/covers on. . .I mean you are supposed to be feeling sick so sleeping in the nude wont help.
That's exactly like having a fever. High temperatures kill bacteria, like
pasteurization, only a fever is more-or-less self-regulated.
Boiling yourself like an egg may help, but it may also cause unnecessary brain damage. So watch out.
