25s are easy to take and i think should be used by everyone for the first time until they get used to what they like... i prefer 23s cuz its less presure on the plunger you have to press... but bro i would never use the same pin twice.. in how you said you just stuck it right back in i believe once you pull it out you never use that agian i dont care that its your own body once you pull it out it hits the air with bacteria and other crap i would just change the pin
