Nudes?

I'm 15 and I've been with my boyfriend for a year (yesterday was a year). I want to send him some *pictures* for it, but I don't want to get in any trouble for it? I took the picture last night and there's nothing in it that anyone could identify as me in it. I really love him and trust him, so I don't have an issue with that. But I don't want anyone to see it when I send it. I really need advice?
