In regards to caring what friends or family think, I can say that before I ever had a real boyfriend / relationship, a couple of times I'd "date" people (and I say "date" because it would never last more than a month tops) and every single one of them, my friends didn't like for one reason or another, and while that's not the deciding factor on why it would never last more than a few weeks, that was a decent part of it and I was self-conscious of what my friends thought of them.
I had an on-and-off thing with a guy I liked for a year, and it was very complicated because I don't think any of our friends liked it and the fact that we have pretty much all mutual friends it made it awkward with the group, but I liked him enough not to care. Unfortunately things didn't work out with him (long story) and one of the reasons he gave was our mutual friends.
But I also met somebody else though him and we also have a lot of the same friends, and some of my friends didn't like him, but I didn't care and didn't let that stop me from hanging out and eventually dating him. So what I was trying to say with all that was if you like somebody enough, it won't matter to you what your friends think of him. Also, it seems like this is the first time somebody likes you or the first person you date? If that's the case, it will be weird no matter what because it's new to you, even if all your friends absolutely love him. Don't worry too much, you get used to it. I'm always quite awkward when relationships are first forming and kind of shy, but then it's just natural and awesome and it doesn't matter what people think. Good luck with whatever happens. <3
