Low sex drive. HELP

Cassandra
My boyfriend has a very low sex drives and it does my head in because I seem to have a high sex drive 
I could have sex all the time 
And its always on my mind 
We have talked about it a few times and he explained it as 
He never really thinks about sex or has an urge for it but he will think about going "down" on me and has urges to do that
Which I love when he does but he thinks sex is just to pleasure me when I don't see it like that and I don't want him to 
It should be for both of us 
Help is there any way to get him to want to have sex?
