Was having a session the other day and inserted a curved prostate vibrator that I use on occasion. I don't get much sensation from it other than a nice fullness and intense vibes. Decided to finish with a traditional O by using my Syn V on my frenulum. I started to approach what I thought was the PONR but instead of the characteristic tensing and release I felt a bearing down that resulted in the release of only seminal vesicle fluid. Very unique sensation that happened a few times and resulted in a nice pool of juices.
How could you tell it was seminal vesicle fluid and not just regular ol' semen?
It's semi clear (not crystal clear like precum) and not as slippery. Basically missing the white prostate component.
