Absolutely anything that interests you.
find some thin common that you both like then talk from there!!
Talk about what you guys can work on so you can work it out. You both should engage in the conversation. It takes two to have a relationship. Good luck.
You can talk about how they are feeling, or anything that they're into.
Discussing intimate details about a partner's body, including their genitals, is a personal choice and varies among individuals. Some people may feel comfortable discussing these topics with their friends, while others may prefer to keep such details private. It ultimately depends on the relationship dynamics and the comfort level of the individuals involved.
You should be able to talk about everything. A boyfriend should be your best friend as well as your boyfriend. So you should be able to talk about planes, cars, girls, boys, family, friends, and everything inbewteen.
talk to him about what he want you to do
the best thing to talk to your your boyfriend about is everything and anything you should be able to talk to your boyfriend about anything and everything and both of you should be able to feel comfortable about any conversations he should talk to you about anything and everything even if its just nothing on your mind you should be able to speak your mind with him.
If you still want to be with him, offer to talk over whatever it is he thinks you need to talk about. If he agrees, the be willing to listen to what he has to say.
About what you guys did that day. Ask him how he's doing. Something you guys would want to do together.
Well, you should break up with your new boyfrien because its not fair to him and talk things over to him that you still have feelings for your old boyfriend, if he really likes/loves you, he should respect how you feel and leave you alone. Then, try to talk things out with your boyfriend because you don't want anyone stealing him right? so you guys talk and tell him that you still like/love him and stuff. If you really like/love him so much, you wouldn't give up any getting him back ;)
talk to that friend.
You probably should talk to your parents about the situation, I think 11 is a little young to have a boyfriend.
