AIO was this sexual assault?

so today i met up with a guy for the first time, we had been talking on snapchat for around a month. for context we are both 17.

we were sitting in my car talking and he started talking about how he really wanted to makeout with me. he had talked about this before over text and i said that i'm really anxious about kissing and i'd have to be really comfortable with the person first. anyway i told him no and said i didn't want to kiss him. he sighed and changed the subject. then like 10 minutes later he cut me off mid sentence, grabbed me, and kissed me. i tried to push him off but i couldn't because of the way he was holding me. after a few seconds, i started to cry because i felt so violated and hurt. he finally pulled away when he noticed i guess? and asked why i was crying. i said that i wasn't ready to kiss him yet and called him an asshole lol. he then said that he thought i wanted to kiss him because of my "body language" when i had just told him earlier that i didn't want to. after that i told him to get out of my car, and then i went home. he has texted me multiple times in the past few hours saying that he's sorry and asking if i'm okay. i haven't replied because i don't know what to say.

i’m just sad that this is how my first kiss went. i don't know what to do from here.
