Inexperienced

I'm sure there is a similar (if not the same) topic here, but I really want to share with you my short story and see your opinions.

In short: I'm 17, I've slept with 3 men so far (yes, unfortunately, they were still over 25) and I haven't had a serious relationship.

I am currently dating a boy who is a person I care about so much for the first time in my life. Everything comes from the fact that he is my age, he treats me great (gentleman in the full sense of the word) so far so good, but he is a virgin. We've talked about this once before, his words were that he wants to be with a person for the first time, who means a lot to him, he knows about my previous relationships. He doesn't have much experience with girls in general, my problem is that I really want to be with him in the full sense of the word. This includes intimate, he knows it, but I don't know how to "speed up" the action this with us, moreover, that my head is spinning thoughts of the kind that if I am his first he will become even more attached to me, I just know that he will never do something first
