It sounds like he's lacking in confidence as a start and needs to explore more of what he enjoys.
However I echo other pps in that it doesn't sound you're sexually compatible.
The question is whether you (and he) thinks maybe more time can be spent between the two of you exploring what he enjoys and what turns him on.
If not, then obviously move on.
It's become very common for young(ish) men to be more turned on by porn and maturation than by real sex because they've spent so much time masterbating to porn, that they become densitised to real sex. You only have to read the agony and advice columns on main newspapers and magazines to see the number of men who write in for advice about this, which should give you an idea of how widespread this issue is!
Generally speaking, the way to move beyond this is for the man to cut back on porn and invest time in having fun with their partners!
If you and he think this could well be the reason why he's just not that into sex and you have strong feelings for him then I'd suggest it's worth sticking with the relationship for a while and seeing if you can bring out his sensuality.
I would also, of course, hope that he's interested in pleasing you too!
If you decide to keep with him for a while, I'd look at heating up the chemistry (assuming you have to start with) without the pressure of penetrative sex...so massages, fooling around, shared showers, kissing etc.
