No, it is not bad to shower after eating; you can eat and then shower right afterwards. You should not swim right after eating.
Why not? I wouldn't look into it further unless you're convinced the whole shower thing is an attempt to tease you. Regardless she has a boyfriend mate.
take a shower and move on
just kiss him and take a shower with him
YES
No
No everyone does it
NO!!
That is very bad indeed. You should be showering every day. I shower twice a day.
Shower her with presents and be nice and show her that you care.
A hot shower is not necessarily, nor directly bad but accidents like slips and falls are increased which may have extremely bad outcomes. There is also no real reason to take a shower because it will not sober you up. Best advise is not to take a shower to avoid these risks.
take a shower!!!!!
