You guys have no clue..of course a few guys use corks as pleasure but.......................
Corking is actually the opposite of what you think
Many straight guys cork themselves in order to show potential Bi or gay guys that they are off limits
Its a protection mechanism and used mainly at clubs, bath houses and steam rooms
If a guy (straight) goes into a steam room and 3 gay guys in there there is a good chance a guy is going to fuk you or at least try as everyone nude so you either show him your corked or he finds out when he tries atomic insertion and then he realizes your straight
You guys have zero clue about sex
