If only he could last longer...

Hello ladies! 
So I've been dating this amazing man since January. He's honestly pretty perfect. One little bitty problem, however. When we're in bed together, he just can't last. And if he does want to last, he can't look at me because he says I'm "too sexy". Any tricks you ladies know of to keep him fully engaged but also last longer? (We do a ton of foreplay, which gets me there, but he still feels bad.)
