Am I selfish?

Of course not!

Being in love is a great feeling and kissing your boyfriend is a totally natural thing to do and want. You probably miss him and since it was your first kiss you only just discovered how nice it is and of course you want more. Don't be ashamed or think it is selfish: he probably wants it just as bad as you do, so when you kiss again it will do both of you good. Just enjoy it.

No of course you are not selfish for thinking this, you can't help that you havn't seen him for a week. Its natural when you have kissed someone to want to kiss them again. Plus he's probably thinking the same and wanting to kiss you aswell ;) It's definatly not selfish because you havn't seen him for a while, and it was your first kiss.

no, i felt the same way when me and my bf kissed for the first time, just be carful and take it slow
