flared-lip cylinder vs. cylinder with sleeve
For pumping, I’ve always used a cylinder with a sleeve for sealing. After trying a few different sleeves I’ve never found one that’s comfortable, especially when removing the sleeve. And more importantly, it seems like with these sleeves seem like my girth expansion and growth would be negatively affected, since the base part of my cock that’s in the sleeve is always constrained to even smaller than its usual erect girth.
Now I’m learning that the better cylinders/pumps have a flared lip, and no sleeve at all - and rightly so, since I wouldn’t have any of the above issues with such a cylinder. But I’m not clear on how a good seal is achieved with these things. If my pubes were shaved, I guess it would be easy enough, using a little lube. But I’m not shaved down there, and don’t intend to ever do it. So would a flared-lip cylinder even work for me?
