I understand why girls sometimes request shower because they must have sensed something uncomfortable.
Please do show your respect and take a shower. It is almost certain that you will enjoy a better time with her.
I have been always trying to present myself clean and groomed and had never been asked to take a shower until early this year when I met Natasha Love.
I had a shower before heading her incall and I also met her before that. When she asked me to have a shower, I was surprised and just told her I did have a shower an hour ago and REFUSED.
You can image what would happen - I got a NON-GFE session
On my way back, I realized why - I had BBQ for lunch and that DAMN onion smell!
