Is this cheating or something I should confess?

I'm using my friend's account btw so don't message me personally if you have questions just write it below.

My boyfriend and I are both 21. We have been together for one year. Before we were official, (we were not boyfriend and girlfriend but we were "together") I pecked a guy friend on the lips without thinking, like in a friendly way to say hello, and on another occasion, I changed in front of a guy friend (I didn't take off my underpants or bra though) because he was helping me pick what to wear (plus he might have been looking away, we were just in the same room). Early in our relationship I was having trouble determining the difference between what I couldn't and could do with my friends, but neither of these incidents were meant to be sexual or romantic. Even though it's been a year since then, I still feel guilty, but I know my boyfriend will think more of this than he needs to. If I found out he did these things at that time in our relationship I probably wouldn't mind since we weren't official yet. I just know my boyfriend tends to get jealous easily because he is slightly overweight and very short and I get the sense that he feels really bad about himself.

Is this cheating or something I should confess?
