First Kiss

I had my first kiss a few days ago (I'm 19) and it was with a random guy at a club. He was dancing with me and he leaned in to kiss and I let him because I kinda didn't mind it but he instantly kissed me with tongue and I was slightly taken back by it but it wasn't so bad. My friends are all making me feel bad about kissing him now but I'm not that bothered that it happend,, their judgement is making me question myself because it's so unlike me to kiss random people :/
