The guy is obviously an ass...Screw him

or fake one..If he wants to be an ass and break up with you for not orgasming....Fake it or screw him....It's obviously his mistakes if he can't make you orgasm...He needs to explore you more and learn what gets you going the most....What a d*ck head

Girl you desirve way better, if he cant please you thats his fault not yours and you tell him that you are the one who should be leaving him not he other way around. Hey its only been what 4,5, months? Whats the attachment?
You cant truly be happy with this guy if he cant please you and if you have to fake it, why not find somewho can satisfy you wholeheartitly, and actually want you to orgasim for you not themselves, make sense?

In my opinion u should find out what turns u on the most, what makes u cum, then tell him how to do it.. Just because he got his other gf to cum, doesnt mean sh*t, they might get turned on a lot easier than u, just talk through him with it and see whats happens.. Personaly I wouldnt break up wit a girl jus because I couldnt make her cum, I would feel a bit incompetant and anxious about it and ask her if it really bothers her, but tbh, if he wants to dump u cos he cant make u orgasm he is jus stupid, but good luck sorting it out..

Your just beginning to discover your sexuality eventually no doubt you'll cum but you'll need time. This guy is a huge dick though I don't see how you think you have the perfect relationship if he said something like that. Hell with all that pressure now I don't think your gonna be able to cum period.
