Please help meeeeeeeeeeee

I want to make out with my girlfriend(she already knows how)but im afraind to because I dont know how.I need advice from someone. and my girlfriend has these mood swings that drive me nuts, one second she is all happy the next she is throwing sh*t around or stops talking, what should I do?

well- dont know.. a kiss though shouoldn't just be a kiss, were you maybe just waiting for the right moment? it think you should just ask her about it.. ask her to teach you.. if she laughs and or makes jokes, she's the wrong one, you could do better.
