getting used to the taste of cum

HOW do i get used to it. The first time my man came in my mouth i was fine and just swallowed it right away. The second time he came in my mouth was a horror show. HORROR. first of all, he kept hitting me too hard in the back of the throat so i was gagging, and also he tasted funky too that make it worse. Then when he came SO HARD AND SO FAST when i tasted a little bit and my eyes started watering and theN I PULLED AWAY CAUSE I STARTED TO THROW UP and then it sHOT OUT AT SUCH A VELOCITY THAT IT HIT mE IN THE FACE AND EYES. And i just sat on the floor with cum in my mouth, hand over my mouth so i wouldn’t vomit and tears streaming down my face. I quickly swallowed bc i didnt want it in my mouth anymore. We had a good laugh about it after, but i am still mortified by that experience, and too scared to gi e another BJ. Let’s just say that, I haven’t given another blowjob since. PLEASE send help.
