I somehow think that you must be trolling all of us.
I doubt anybody can be this stubborn or this hung up on taking a 5 min shower or on losing that amount of time.
Being intimate with a woman is not about how much maxime time you can manage to fuck.
Having a lady be at ease with you and trust you is a prelude to a good session and for them knowing and seeing that you are clean is a must.
Take a fucking shower each and every time you see an SP regardless of when you took one at home, is the best advice you will get.
