I think suckable cock is the one which you can fill in your mouth.

My perfect cock to suck would be between 4-6”. Big long cocks just don’t do it for me, I like an average stubby rock hard one to suck on

Mine's ~1.5-2.5" long x 3.5" in girth when soft & ~5.75" x 4.75" when hard. That's 0.59" above average erect length & only 0.16" above average erect girth. Even though it's well-within the average range, I've had a few girlfriends gag on it while giving me head.

To me a "suckable" cock is any cock 7" or over, but maybe that's just me

By and large I'd say the answer is "a qualified yes". I'm a dedicated cocksucker who given probably eight or ten thousand blow jobs to two or three thousand different men, so I know what it's like to have a cock in my mouth. The jumbo size cocks are fastinating, but it is virtually impossible to give them proper oral service. The best sucking size are cocks ranging from somewhat smaller than normal to normal. These are a satisfying mouthful but not big as to trigger a gag reflex. Even very small cocks are fun to suck, far better than the jumbos.

So, Mr luca85, enjoy your modest size penis and be proud of it. And keep making it available for cocksuckers to suck. We'll thank you.

A suckable cock is any cock regardless of size that a person may deem nice enough that they want to suck....and therefore suckable. With that said, a cock might be too tiny to suck or too huge to get in one's mouth that the term physically suckable may not apply. Today's semantics lesson.

6 inch and under is nice = get the whole cock in and really work the shaft

I'd say, it depends on who the cocksucker is! I personally like em 7" to 8"s with a wideer shape!!

Dont over think it ... Take it as a compliment
When I say a cock is suckable ... I mean Dayum I want to taste that cock!

women love to suck my cock. Though they usually cannot swallow the whole thing. It seems to help them get wet and ready for intercourse. Of course I find that 69 is the best way for that.
