My girlfriend of 2 months has never had a boyfriend before me. We are both seniors in high school and I have had 2 other previous relationships. Now her first kiss was with me, and it was a nice little kiss on the lips. Since then, thats all we've been doing...is single closed mouth kisses, even when we're laying together, we just have momentary kisses.I want to make out with her and open mouth kiss her, but she has never done it before, and im pretty sure she isn't sure what she is supposed to do. I feel kinda awkward asking her about it, and it would be weird if I were to 'teach' her, but I just don't think she will catch on.How should I go about getting her to do this???
