Hey all, I recently decided to upgrade my pump from the shitty 30 dollar one on amazon

Im looking at cylinder sizing and trying to figure out which size is best... cause I am about 5.5 around girth near the top, but about 5.0 around the base (bat shape lol) , or a bit bigger sometimes. My dick curves like slightly up and to the left ... does this change the tube size i should get? Also i noticed my dick like gets stuck on the sides of the cylinder - the head of my dick that is - ive figured out if i put a small amount of thin fabric sleev on my glans then it prevents it from that uncomfortable skin catching...

Also what tricks can i use to keep the suction on the bottom tight ? i have a silicone sleeve thing, but it was letting air in and sometimes would suck in my skin anyway and id have to stop and repump it a few times trying to get it to not get skin in from the balls
