I Get Dry Fast When Having Sex With My Boyfriend,

I get dry fast when having sex with my boyfriend, we don't last up to 10 minutes and I just go dry, my performance is really bad on bed ,could it too much intake of sugar because I take a lot of sugar. .He has atleast opened up to tell me he dint enjoy our last sex and I feel so sad about it,looking back at my previous relationships I never use to get dry fast like ds . Please how can I improve my sex performance for us to enjoy it and what really makes me go dry fast. Thanks
