Hi Sarah, what do you want to do. It depends on who you are kissing. Do you love the guy, is he just an acquantance, is it passionate, or would you like it to be so. Move a little closer, he may take the lead, and you may not want to do a lot beyond kissing,,,, kissing can be light or it can lead to different levels of sexual contact, but that's not automatic. It depends on two people... Is it someone you are used to kissing. I don't know your age so its differs too, and how close you are to the person, for example in love with them...Every guy is different.... Some treat a girl well, others might even want a lot more than the girl want to give.... Anyway, enjoy the KISS, and hope this is useful.
