He kissed me twice, I wasn’t prepared.

Ive been recently getting close physically with my guy friend. Long story short we were on the bus together - prior to this he was hinting about kissing but I was shy and didn’t really fuel his thought. Anyway, we get on the bus and he sits us at the back. We go quiet for a bit and he says my name. I respond with sticking my tongue out a bit as an inside joke we do, then he does the same but suddenly holds my chin, leans in and steals a kiss (a peck). I saw it coming but I didn’t really think he would do that. He keeps apologizing and trying to explain why he did that but I kept reassuring him. He asks me if Ive ever deeply kissed anyone since my last relationship and I respond with no. (Ive never french kissed anybody - I don’t know how). So, a few minutes later we are speaking and out of NOWHERE and unprovoked he kisses me again but this time with tongue!! I felt my body getting tense and struggling to even open my mouth a bit and I said against his lips, “i don’t know how, im sorry” Because I couldn’t kiss him back, I had no clue how. I pulled away as I said that. I feel so embarrassed but at the same time should I even feel apologetic to being inexperienced? I wasn’t prepared at all. He rushed off the bus afterwards but apologised later on again saying we should act like nothing happened - and that we are just frends
