Help! SEX issue

Mei
Me and my boyfriend are very sexually active people.  He never had a girlfriend before and always relies on porn, but until he met me; now he stopped watching and was getting attracted to me, which worked. 
He gets hard when I do the little things like kissing and cuddling, but the issue is during sex he is unable to multitask and is always anxious; he feels bad that he can't give love to me and needs help. One reason is it's his first time and he needs to be relaxed to get hard.  Anyone have any suggestions to solving this case? Please and Thank you :)
