how can i be more comfortable in a public intimate relationship?

i’m 22 and have never been in a relationship, but i’ve met this guy that’s intertwined in a huge mutual friend group, so all our friends know we’ve been fooling around and going on dates, we’re not seeing or talking to anyone else but we’re not labeling anything yet, this is mostly because of me lol

anyways, i think he’s fucking awesome, he’s funny, thoughtful, handsome, witty, a great musician, and literally the most charismatic guy i’ve ever met, some of our mutual friends and some of my personal friends have goofed on me for getting with him simply because of his looks, i honestly think he’s beautiful, he is a bit of a bigger guy but ive never cared about that sort of thing and i didn’t really realize people would judge me for looking past something like that? anywaysss due to multiple people telling me their opinion has unfortunately turned me off from being more of a thing in public, but were ALWAYS with friends so it ends up really distancing us, i really want this to work and i know i shouldn’t care what people think or say but i can’t help it
