Im 14 and I feel really bad because I have a boyfriend for about 6 months now and we were best friends since I was 12 and I really love him and I was at my friends house and we were drinnking twisted tea it has some alcohol in it and I guess I was a little tipsy and me and her were laughing and then we kissed for about 5 seconds and then I pulled away and I went to the bathroom knowing that I had cheated feeling guilty as ever crying because I know that I have ruined something very special in my life I cry every time I think about it. And I am not blaming her or the alcohol it was my fault I'm taking 100 percent responsibility and I wish I hadn't but I did and I feel really guilty :( I am going to tell him but the longer I wait the worse its going to be but I just really need someone to talk to :'( it been about a week and I need to tell him in person or should I tell him on the phone ? And what really kills me is that he's the first guy who has ever treated me right and been 100% faithful. And I love him I do.

You are 14 and he is the first guy who has ever treated you right? Please, concentrate on friends for another 2 years. They are who stand beside you when romance falls on troubled waters.
Don't worry about the kiss and don't even mention it - unless it meant that you were romantically interested in the girl. Don't you see people kissing on the lips without it meaning sex? I've even seen parents kiss little kids on the lips. I don't know why you think this requires some big confession. If you did 'feel something' or if it made you curious to find out more, then find out within yourself what is going on before telling him. If not - let it go as nothing. It's really only our culture where men and women are so hung up on affection between two people of the same gender who aren't gay.
