FWB no orgasm

Hi everyone, please help!

I recently lost my V card and the guy I'm having sex with did not orgasm after we had sex for about 30 minutes a few days ago. This would be are 5th time having sex. I asked him if I did something wrong or if I was too wet but he said it was because of him watching porn. Could this be true or am I at fault?? Please help I am starting to feel so bad about myself after sex that day.

Thank You!!
