I don't know about normal, it depends what you consider normal. There is normal as in "what everyone thinks is normal", then there is normal is in "what majority or large percentage do", then there is normal as in "what scientists tell us", then there is "what media and other authorities tell us" and so on.
As for me, I prefer to ask myself - what is NATURAL.
It is natural to have an orgasam and to go through that wonderful experience when you have sex, or when you masturbate.
Do you masturbate? If not, then, of course it would be hard to enjoy sex to the fullest as you've never really done it yourself. It's like never cooking your own food, but complaining that your cook isn't doing a good job ... or something along those lines.
Educate yourself about orgasm. Learn all there is to learn about sex, G-spot, orgasam, but be carefull- there is tons of completely wrong info out there! Usually newer publications and texts are better, and stay away from famous personalities like Dr. Lora or dr.Ruth.
Before you can enjoy sex to the fullest, you need to learn to relax; just read the previous response you got - it illustrates perfectly how important it is to learn to let go. We are all brought up completely stiff and petrified not to make a mistake. In sex, it is the opposite - you have to NOT care, and then it's a real pleasure.
