Never kissed before, best friend just told me he would teach me

Im in high school and never kissed before, my best friend and i always talk about relationships and our crushs on other people, and even though we tell each other "i love you" i've always considered it all platonic. I like this boy and my hb knows about it, he just sent me some drunk snaps and confessed how he had wanted to kiss me before, and if i ever wanted, he would teach me how to kiss.

I have thought about asking him something like that before, but i dont know, it feels wrong, and i think i shouls give my first kiss to the right person, but its not like my best friend is the wrong person, and if i were to kiss the boy i actually like, i would do it right. I need advice on what i should do, should i ask him to teach me or just forget about it?
