My boyfriend doesn’t last long.

My boyfriend and I enjoy sex as I’m sure any other person does, but we both have an issue. My boyfriend seldom lasts very long. He recognizes he has a problem, but it wasn’t until this morning that he actually said he needed to talk to a professional about it maybe. He feels bad that he can’t give me what I want because he doesn’t last long. Now generally, we go for “two or three rounds” as he calls it. So even if he cums after a minute, we’ll take a short break and go back at it. But sometimes he can’t because he feels super tired after it, or even sick like this morning. He became nauseas and was very upset because he said he only lasted like 5 seconds which wasn’t really exaggerating. He put it in and yeah 5 seconds later was done. What can he do, and who can he see about this issue? I always reassure him that it’s okay, and that I still love him nonetheless. But it’s really bothering him.
