Wow! So much here. Hard to decide what to contribute.
I have always LOVED a bj... but, I never expected release. I masturbate a LOT and know how hard it is for someone to really KNOW how to get me "over"... I usually don't cum from oral. I enjoy and get lost in the process... but, I am a balls man, like mentioned earlier... I can get lost in someone licking, sucking my balls much more than the actual sucking of my cock.
That said, there have been a few guys (5) who have hit on all targets... and for whatever reason managed to get me off.... is it style or is it prowess... or both?
What is strange is that I consider myself a MASTER of sucking... and BTW for some reason (no slight intended) I ALWAYS manage to get "the straight guy" off... I always thought it had to do with the fact that many women wouldn't "do that"... Now, I know the women on this site are open and love sex, but there are many who aren't (I married one... and had to teach her about her genitalia, as she had no clue.... and how to enjoy it)
Then, I realized something.... WATCH MEN... they massage the base of the glans, but rarely the whole thing. Circumsised men almost NEVER cover the head with their hands... It's always tugging just at the head.... Uncut is different, because you are pulling a nice viscous layer over the top... but watch them too... they GRAB just at the beginning of the head and let the rest just happen.
My ex had "the slit" version of circumcision... I found with him that the spot that he was circumsised (the line itself) was the nirvana point for him... and just a gentle massage of the underside of his cock and sucking that line brought him to his knees... Literally.
Most straight films I see have the woman anxiously sucking "the head"... it won't work. Many cocks later, I've discovered that gentle massage of the head is great, but the frenum and shaft are most important....
It's not about sucking the head... it's about enjoying the WHOLE cock. And that "jumping off point" will not be found in paying too much attention to one thing (specifically the head, which too many people fixate on entirely)
And yes... despite being gay, I had had enough training to know how to bring a woman off orally... I lost my virginity and brought the brave lass to THREE orgasms at age 15 (she was 20), with her grabbing the bedrails and thrusting her body into the air.... She accused me of having slept with other people, and I assured her I'd only heard stories at the diner and ran with them.
