May I start by saying there is nothing wrong with you, and the "woman-not-orgasming-during-penetrative-intercourse" is a rather common concern for couples and there may actually be two issues here:

1) Is he is insisting you have to have one with male superior intercourse? Your boyfriend has his sexual enjoyment, as do many men, tied to the performance-based objective of YOUR orgasm. That puts performance pressure on both of you. Does he feel he hasn't been man enough for you? If you are sharing your body with him that should be statement enough that he is man enough. The following are some common reasons why he may feel this way; Because that is what happens in adult films, is described in magazines, and or that ALL of his other girlfriends did. If so then he is trapping himself and you in a tough place. Also FYI the reason the majority of women fake is they know nothing is going to happen, they fake and give men the impression what they were doing worked. Hence faking orgasms gives your future experiences with him and any women after you unrealistic and false impressions.

2) Most women orgasm most easily via oral stimulation. Reason being there is the soft warmth of the mouth along with the constant stimulation that most women require to orgasm. If you have experienced orgasms before likely he is not doing what is needed to achieve them whether that is with any body part he has, between his legs, his hand, mouth, or assisted with a vibrator. Have you shown him what works best for you? Do you know what that is?

Also adult films are men marketing to men about what works visually for men they invariably forget to include the interests of 50% of the participants, the women. So if this is a major info source it is inherently inaccurate.

Better to have a pleasure based sex life than a performance based one.
Trust this helps.
