Is it normal to be nervous about being with another gay guy?

So a little while back I made a secret instagram that told my sexuality so I could meet more people, other than family and friends like on my regular one. I got messages from lots of cute guys and girls the week I made it and started posting pics. Then one day, I get a message from some guy who said I was cute, but, at the time, I had no attraction to him. So after exchanging snapchats and all, we started to text and swap nudes (you know, the usual gay thing). However, I soon realized that he loved me, but at the time I didn't love him back, so I kept it strictly "friends with benefits". After a while though, I became fond of him and actually really started to like him to the point of telling him that I loved him back. Now we're both in love and I want a future with him and he really wants one with me, and I'm planning on moving upstate to be near him once I enter the military. I'm just nervous about the whole "relationship" thing. I'm not officially "out" to my parents and very few of my friends know. I'm also nervous if he'll find me attractive and often times I have told him the I'm very unnattractive, but he thinks I'm cute and we've facetimed and sent pics, so it's not exactly a mystery what I look like. I'm just REALLY nervous about being in a relationship with him because I don't know if I'll like/ feel comfortable with living with someone else, and if I do, I don't know if he'll want to persue the relationship further as to meeting each others' family and parents or even getting married! I have no idea what to do and I'm nervous about him, (I get nervous every time we talk on facetime) and I'm nervous about my family finding out that I'm bi (more gay than straight, but still bi). I've let him know about my fears but he is really supportive, but I don't want him to get upset and break up with me because I can't fully commit like he wants to. On top of that, we're like complete opposites. I'm a skinny, pale nerdy kind of guy and hes a tan, sporty, partying kind of guy. I just am so NERVOUS! Please help! Any comments will be appreciated!
