How to orgasm multiple times?

When my bf and I have sex I can literally orgasm in minutes if he does it right which he knows how to do by now... but it’s such a problem because I can’t do it multiple times!!! It’s like all the sexual energy has been released and I cannot have him inside me anymore!! I tried again a few minutes after but I just couldn’t get it in, I get so turned off after I orgasm and he gets really turned on when I do so he makes me orgasm anyways even though it’s going to end😂 has anyone been able to orgasm multiple times after not being able to before?
