My bf lasts too long

I always end up coming at least twice before he does and you may be thinking that that's great for me but after I come I kinda like...get out of the mood? And I have to get into the mood again, and I have what I thought was a normal amount of stamina but apparently not because I get super exhausted before he gets to come. He says I'm amazing and that it's not me 'being bad at anything' but idk what to do still, any tips?
