I've got to back up ... the question was if I washed my mouth. No. My hands and face after the bathroom, but not the mouth. I think I mis-read the initial question.
Usually I do wash my mouth out, but if it's been such a pleasurable and memorable one, then leave it (for the memories). Besides, we all have to remember it's only nature at it's very best!
Not especially.... once we are completely finished love making I enjoy a shower and wash my mouth out then... but during... nope not normally..it would waste precious time in the moment of passion. Unless my partner wanted me to i wouldnt.
