Talking about anything related to sex can be embarrassing for people. Chances are, if you have questions or want to talk about something, your friends do too. Regardless of your sexual orientation, it's always a good idea to know about your birth control options after all, most methods have benefits other than just pregnancy prevention.
Ease Me In (The more guarded approach):
I know this is awkward, but you're the only [person/people] I can talk to about this. I am mostly interested in girls, but I want to be educated about sexual health and all of the options for protection. I was wondering what you think about birth control. Do you use it? What do you use? Why do you use it?
Just Give It to Me (The no-nonsense tactic):
I just read that more than half of pregnancies for women in their 20s are unplanned. It definitely made me think: what if I do end up having sex with a guy? What do you think about birth control?"
