Am i the only one who thinks that kissing is not that deep?

(English is not my first language I'm sorry) I'm going to be completely honest, when i turned 15 i was going to parties and making out with people i just met that same day (while drunk btw). 

My "friends" started calling me "easy" (and i get that, it makes sense) some even called me a "slut". But the guys were the ones that kissed me, and i was always too nervous to reject a kiss.

 as an example. I've never dated anyone back then, but at one of those parties I happened to come across a guy i met through Instagram, we decided to talk since its the first time we interacted in person. at one point he leaned in and kissed me (no offense but he was not my type), i didn't get the courage to push him away. specially because things would get awkward, there were mutual friends around, and i did not wanted to leave yet, so we just started making out. Later, when I decided to leave, i told him in private that i don't think i like him that way and i wouldn't like him to do that again, and that we can still talk as friends if he wanted to, but that's his decision to make. (which is usually what i do after someone who I'm not interest in kisses me)

i didn't think kissing was "gross" nor an "intimate" action.

Another situation that happened to me: when playing truth or dare w my friends (15-17 y.o.) they always gave the kissing dares to me. and i just did it. (pretty boring dares ik) and when my friend asked me why i always do it without complaining, i tried to explain to hear that a kiss is just a kiss, it means nothing to me, its just a superficial thing. but they always misunderstood me and thought i just cared for REAL intimacy (sex) which was not true, since I've never had the intention to have intimacy until 18 (present).

 Does someone feels the same way or am i just being irrational?
