I am seeing a guy while in a relationship?

[ESTRELLA]

Hey,
I am a 15 y/o girl and I am quite mature and responsible for my age.
I have a boyfriend (18) since 2 weeks ago, and we have been doing stuff since the end of november.
Now, I also met this guy (20) two weeks ago. He followed me on twitter for a year and then we started talking. He wanted to meet quite quickly, but I was okay with it and went to see him. At the end of the date he kissed me twice and ever since he has been in my head. He is so charming, even though when I saw him again yesterday he kissed me again, but when I told him I would rather not kiss because I have only seen him twice and I have a boyfriend, he told me he doesn't see the point of our dating then and acts like I'm a young child because I don't have sexual experience or desire.
What should I do?

Nothing about this sounds right. You're cheating on your boyfriend, which is a crappy thing to do.. and also, the guy you're cheating with is clearly using you for sex..

You are a troll, did you grow younger since your last question where you were 17?

Honestly you are WAY too you g for the 20 y/o he needs to get a damn life. And you are already in a healthy relationship don't screw it up. The 20 y/o says your a actin like a child because you don't want sex? Shows what he thinks about. That's all he wants from you in my opinion.

If you were "quite mature" you wouldn't be seeing two guys at once. Mature people can make a decision, and they don't cheat.

He acts like you're a child because you're acting like one - wow - he has good sense. Pity YOU don't.

the guy from twitter is a creep that wants to have sex with you, plain and simple. Dont talk to that guy ever again.
if you really were mature for your age you would have realized this straight away, actually you wouldn't even be meeting 20 year old guys off the internet.

'quite mature' and then you say your kissing 2 boys righy... and then a 20 year old guy is kissing a 15 year old ? that guy is stupid and can go to jail
