A Friend Of Privilege.

Hi! I have written a lot here, and since I have received understanding and advice, I have decided to trust you again and tell you what I am going through right now and ask for your advice. I guess it's going to get a little long post, but thank you to everyone who's going to spend their nerves and time reading it to the end. As the title goes. I have a friend with privileges. We've only been together twice recently, but soon the 3rd will come and I'd rather have to deal with myself early before things get messier than they are. Let me mention that I'm 18, I'm not that small, which I'm not saying I'm big with, but that I'm responsible for what I did. So the boy in question and I turned 7 days old since we've been friends. He's my best friend, one of my closest people, and we love each other and rely on each other tremendously. He and I have had trepidation since we met. For me, the thrills were much stronger as it was my first love or the first boy I fell in love with, whereas there was more interest and investing so much. We had leveled those feelings after I had a couple of boyfriends and suppressed my feelings for him. Finally... nearly 2 years, we came to terms with the fact that we preferred our friendship over feelings and decided to indulge in the anchoring of our friendship. After growing up a little and coming to the maturation years, we started writing on more intimate topics and always joked about the fact that one day we would do it, we just have to kiss first. He's not a typical boy player or a number. He's extremely shy and dares I say even that I taught him how to talk to girls and even something like a little bit like saying the word 'sex'. So that's a problem sometimes because everything that's supposed to happen has to happen through me. I mean, I do the first, the second, and if you're going to take the third steps. Two weeks ago we were at his house and it happened that we kissed and because there was a lot of desire and literally sparks were flying, we made out a little bit quite thoroughly if I could put it that way. After that, I thought we wouldn't talk, but on the contrary - everything was normal. We just didn't mention what happened. After a week it happened again, but for a short and much more restrained, because I had no desire. And that's where the complicated part comes from. He's got a girlfriend. We're not close to her, not at all. We've seen each other once to meet you, and that's it. She's in another city, which is good. But it bothers me that we're not doing the right thing against her. She doesn't attract him sexually at all, they only get to kisses, and she relaxes with me from the first kiss. I don't know what this is about. I guess it's because of the desire we both feel for each other. We haven't had sex, but I think that's going to happen someday. What do you think, should we continue with what we both want and want for years and indulge at the moment, or do we have to sever this relationship for his girlfriend? We talked about it, but we're both pretty confused, and I think the decision should be made because he's the bound one. Please give advice any, even criticism. Thanks for your time. Please don't pass by reading only. :)
