Do you swallow or spit?

Whenever I give my boyfriend a BJ I'm always too nervous to let him cum in my mouth so he always lets me stop before he gets too close. Sometime soon I wanna surprise him and let him cum in my mouth ☺️ but it'd be my first time and I'm not sure what I should do! To me, swallowing it seems the easiest. But will he think it's gross if I swallow? Spitting it out just seems like a hassle cause you need to make sure you have a tissue or something to spit it out in. Give me your opinions and let me know what you do :)
