TITLE: Me [18M] dating [23M], 3 months in and still doesn't want to use the word "boyfriend"
POST: I've been dating a really great guy for about 3 months now. We pretty much hit it off on the first date and have been seeing each other often.

We were sitting down one night and I brought up the conversation about 'where this is going' and he said that he really likes me and sees us going in a good direction but isn't "ready" to put a label on it yet... I just don't really understand this thinking because we do a lot of couple-like things together, we've met each other's friends and families and go on trips out of town together, he even invited me on holiday with him next month.

I know he still has issues with his sexuality and I'm wondering if this is the reason why he wants to go slow? I'm just really insecure because he's a lot more attractive than me so I feel like someone else could easily snatch him up. I feel like I'm starting to fall in love with him if I'm honest.

I just don't want to end up getting hurt I guess, I don't think he would hurt me. I just want to know that I'm his and he's mine, I'm not asking anything too extreme of him like posting it on facebook or shouting it from the roof tops.

I just want some advice on how to move from here, my plan was to basically wait a few more months and see how things go, and if he still feels the same we may have to go our separate ways.
TL;DR: 
Guy I've been seeing for 3 months says things are going well but doesn't want the label of "boyfriend", despite acting like a couple, could this be to do with issues surrounding his sexuality?
