Getting back to the main subject, YES! Getting to the "Are adult pacifiers too big" the Nuk # 5 was great for me, till my "Bitch" wife threw it out, can't blame her tough.........!
I have always wanted to suckle a breast. My first love, when Iwas 19, held me to her breast to suckle as she brought me to an ejaculaton, with her hand that I will never forget! I pumped out more cum that night than I have never done since!
Fast forward now in my 70's when in bed and sucking my thumb, and I get into the fetal position, it is almost like I am in a trance.
I start sucking my thumb much more aggressivley. The next thing that happens is my whole body starts trembling, shaking, & quivering just like after an orgasm with my wife, years ago !!!
Also I love my pacifier's as the gard makes it feel more like a breast than my thumb!
Oh it may also be that i am an AB/DL 😃!!
