Birth Control?

I'm 16 (Virgin) and I'm not sexually active but I know I get those urges to do things but I hold my content out of respect for my mom and the fact that I'm not on birth control. I do have a boyfriend who I've been with for 2 years almost 3 and he's not a virgin and he has condoms. He doesn't push me into having sex or makes me do thing I don't want to do. He really respects the descision I made to wait until I felt like I was ready to...now that I am having those feelings i honestly don't know how I want to tell my mom that I want to be on birth control...😫 can you guys help me!!!!
