How can I get my girlfriend to give me a blowjob

I’ve been dating my girlfriend for over a year now and she has never given me a blowjob. I find it weird because for a 15-year-old she’s very open about sex and isn’t nervous to initiate it or sexual actions. I’m 16 btw.<br><br>I’ve tried hinting and asking her if she’d like to try but she’d always just give me a weird look and make it awkward. I’ve been thinking about asking more about it instead of just hinting but I don’t wanna make it awkward. I also don’t wanna ask her friends because I find myself a very private person and I don’t want her to know.
