You have been going out a while so you two would know each other. Don't feel under pressure to kiss this girl. You should wait until you are ready and when you are ready you should do it. She is shy so she is probably waiting for you to make the first move. Go for it.
You can I'm surprised that you havent kissed her yet I kissed my boyfriend allot when I was that age just make sure that she is ready for it:)
i think you should you should be able 2 trust your girlfriend!!!!!!!!!!!
well if he kissed you you just have to tell him, that was nice and that you like him and he might brake up with his girlfriend
Honesty is always the best policy. Come clean to your girlfriend.
Unfortunately she has moved on and so should you.
You're jealous, so back to her.
Hit him
yes, you should tell her. if you are important to her, it shouldn't even matter that you've never kissed anyone.
you should say sorry then smack him in the face and run away from him
Then you should ask yourself these questions, "How did I feel when we kissed?" "Did it feel right?" "Is she right for me?" These may perplex you but it is one way of knowing if you want to kiss her or not. If you really do love your girlfriend and are very passionate, you should try to kiss her when it is the right time. Maybe you should ask her to come to talk to her and then kiss her passionatly. You could wait if it's not the right time. Kissing comes naturally and you know when to pucker up and move your lips. Give it to her good. Hope this helps.
Ask them to be your boyfriend/girlfriend (i dunno which gender you are so...)
Go your separate ways as he is taken and you need to keep your distance from them - kissing was very wrong on both your parts.
