My boyfriend admitted to me he has a low sex drive

I’m really confused right now. I’ve been dating my boyfriend for 3 years and we started living together 5months ago. Lately, I’ve become so sexually frustrated because we only have sex once a week and it last less than 10mins. I definitely need more. I’ve tried everything from talking to him to trying some sexy foreplay, nothing seems to help. Last night he flat out told me he does not have a sex drive, I didn’t know what to say. I don’t know if it’s the age difference (I’m 24 he’s 36) but I’m not sure how much longer I can take this. I don’t want us to become sexually frustrated roommates.
