I think we might be the victim of someone with a poor grasp of English or someone who used an on-line translator to translate their problem to English.

Sex is sex whether it is a blow/hand job or vaginal sex.
When you saying playing with her what do you mean? Do you get her off? Or is it just enough to get you hard?
Do you manage to get hard and get off on your own? IE, masturbate? Is there something that she's doing that you don't like?
For example, I have only met on woman who can get me off via blowjob, who is thankfully my wife but not the reason I married her, and only one that has gotten close with their hand. It can be off putting because they're doing something that you're not used to and you're not sure that it is going to get you off.

I'm not angry or up-set at this because I am an acceptance person, but I do feel sad whenever she tried so hard; demanding my load but I have not gave her a single load since the day we first making out, which has been almost a month, then got up-set and keep comparing me to her ex. We've usually making out 2-3 times / week. (Not intercourse because I respect her request of "virgin marriage").
Being uncomfortable, no matter how turned on you are will hamper things. As well you have the added concern that someone will see you.
I can understand why she would be upset and she DOES NOT have the right to be upset. She's upset that she can't get you off. She believes that, with her skill and ability, she should be able to get you off. That someone like her could get anyone off and since she can't get you off there is something wrong with YOU and not her. This is a common misconception. Everyone has their own preferences and need to teach their partners how to get them off.
That being said, her comparing you to her EX isn't a good thing. This is insulting to you and the beginnings of power games in your relationship. You have to tell her that this isn't acceptable. It will hurt your relationship and eventually end it. You have to wonder how many times she compared her EX to the EX before that.

Much appreciate for all your helpful replies.
I would leave her. It sounds like she's a toxic person. I am not sure anything healthy can come of this.
What you need to do, if you wish to continue is to talk to her and train her to get you off. Don't rely on her skills because they're not working. She needs to learn this.
Good Luck.
