Starting to date again

I met up with an old friend this weekend and we really hit it off – I enjoy his company, I look forward to his texts, and he’s coming over Friday to make me dinner…
BUT…He is very skinny (making me worried I will feel big around him), he has a neck tattoo which I don’t care for much, and he’s a drummer in a band (angry music that is not my style)
SO how do I look past all this? My thoughts seem to say “that’s not the type of person you’re supposed to be with” “he’s too skinny” “what will other people think about his neck tattoo?” as I’m writing this I’m realizing why do I care so much what other ppl think?
