<human>: Can you summarize the given text in a few sentences?

I want to get on birth control in case my boyfriend [16M] of almost 5 months and I decide to have sex. We've done other sexual stuff and while he is able to get condoms it would obviously be preferable for me to be on birth control in addition to him wearing condoms, so I don't really want to have sex unless I'm on the pill. Being 15 I am not able to get the pill myself but would need my mother's help.

   What I need help with is if/how I should ask her. I just don't know exactly what her feelings on this are as my parents have never given me the "talk". I don't think that she'd be too upset (she got my older sister an STD shot no questions asked when my sister asked her for it, and she walked in on me and my boyfriend doing stuff and didn't say anything to me about it, I didn't get yelled at or in trouble at all). I'm just nervous and not exactly sure what to say.
