Looking for help

Hey there I'm very bi-curious and have tried it twice. My gool is to try letting a guy shoot his cum in my mouth so I can taste it and hopefully swallow it.
The two guys couldn't cum because they were nervious so every time I want to try this agian I think I might not beable to go through with it now if they do shoot in my mouth.
Anyone know is it a hard thing to do as in swallow or taste?
