“But I don’t believe her.”
Damn. Some people deserve lifetime celibacy.
Now to the revived thread, obligatory: we now have ask a woman, so this isn’t a woman’s issue.
However, it can be simple physics.
Lie face down on a massage table with all legs of equal height and congestion happens.
But when I shorten the back legs by a notch, my clients have much less congestion.
This is day-to-day knowlegede for me.
So applying it to slurping peen, if I’m above and angling my face down, stuff drains to my sinuses, or, what’s there gets to a point where it seems they are more full, and the body tries to eliminate the excess.
