after joking about it for so long with me bestie, we actually did it 6 years ago

Of course, I’ve done it in a purely non-sexual way. Kissing someone of the same sex doesn’t make you gay :P Silly people. I’m still as heterosexual as ever.
You boys are lucky, girls are much better kissers, in my opinion. ;) Go for it. It’s not like in the movies where they sit around for like three hours and then they snap at exactly the same time and decide to kiss. Initiate it by getting a bit closer, start hugging/touching..whatever she likes. Don’t go for the lips straightaway. Start with cheeks/necks..etc. Then go gently, however much you want it. She’ll most likely want more if she likes you.
If not, oh well…:( Try with someone else. 6 years ago
