HELP!!!

I know people are going to say "you're too young!!" I'm 15 almost 16 (in July). But I've been having sexual urges for the past couple months and I don't know what to do. My boyfriend and I have done things together but we've never seen each other like that. We've been together for a year and three months and we were very awkward around each other when we first started dating. I've been on the pill for about a month (I started the pill because my mom said it would help make my period less heavy and reduce my acne) and my mom said to tell her if I started having sex. She also told me to tell/ask her if I wanted a vibrator (but that was before I started dating) I don't know what to do....
