First of all, how long were you in the relationship? Have your feelings for your mate decreased? What is the attraction that you have with the new boy? Is it just physical or more mental? I would evaluate my feelings for your current love interest, and see if it would be worth pursuing some one new.
no cause then it would be boyfriend-boyfriend
its possible, but it might lead to major relationship problems if the girl that's dating the boy finds out
That you want to be in a relationship with him or another boy
It means that he isn't ready for a committed relationship.
If a boy you like kisses another girl, if you really like him be happy for him!
You should not try to go further to start a relationship because he already has a girlfriend. You should wait to start a relationship with him, if a relationship is what you are seeking, to avoid interference with his other relationship. Also, if this boy likes you and expresses it to you, do not feel as if he completely likes you. Keep in mind he has another girlfriend, that most likely thinks her boyfriend is loyal to her and would never like a girl in a way that he is supposed to like her. This boy seems to be the type that would possibly cheat on his girlfriend.
If you are not steady dating the boy you like then yes, perhaps flirting with another boy will make the other one jealous.
Maybe they are simply telling the truth and they feel like they need time to get over the last relationship before starting another one.
If you like someone better, then be honest and break up with the boy you are dating.
You don't. You need to take the time to get over this person before you can move on to another relationship. When you find someone else like them for them and what they have to offer - don't compare them or try to get them to be like someone else.
give him a blowjob
not technically, if he is really interested in you and you bring your relationship further it mite turn into love. if he likes another girl.......well i would move on
