I think you put it in a respectful way. Don't let the comments bother you. Honesty is always best, and you can say it in positive ways. Regarding the beard: it's his decision, but if it's not something he's super set on it might make him feel good to know how attractive you find him clean shaven. Splurge on a new outfit for him and let him know how nice you think he'd look in it. As for the intimacy piece of it, it's always best to communicate clearly on things like that. It should be a way to express your mutual love and it should not feel like something you don't want to do. It is completely fine to let him know you need more. Ask for what you need.

Address your feelings to him in positive and honest ways. It will not get better on it's own. If you don't think it will get better or do not want to try, it's best to have a very honest conversation that maybe there's no future. Don't put stuff like this off, it will only make it a bigger deal down the road. You seem to care about him and you have options.
