How was your first time sucking dick?

How was your first time, I'm wondering because last night..well early morning I tried 69 with my bf. I was really scared and nervous I'd hurt or bite him, which I didn't. So this is the first time I've ever done it and he seemed to like it although I felt like I was going to be sick a few times but carried on. He decided that I do it without my hand which I did and he was thrusting up into my mouth slowly then pushed it right in causing me to choke..I was certain I was going to vomit then, he found it really funny😏lol so how was your first times, and has ur so ever thrusted into your mouth too far and made you choke?😂🍆
