Why does a guy have an erection problem?

We met on the Internet, everything was great in correspondence, the first dates were also great. The infatuation and sexual tension between us is at its maximum and it is mutual, one glance shows it. But in the end, the first night was a failure... He was standing up and falling down, I couldn't come because of it, and neither could he. I wasn't too upset, I thought that it happens, we got overexcited and expected too much. Although he said that he wanted to cum and after he masturbated next to him, he finished. I referred to the need for lubrication (I won't say that I flow like a waterfall during sex, but usually everything went well without it).

We bought a lubricant, I wouldn't say that he had a stake, but we finished. The next time we watched some movie where there were a lot of bed scenes, it seems to me that it played a role, plus I told him how I liked it and it seemed to be more fun.

Then some bullshit again! He was constantly falling down, he kept saying that he needed to take a break, and with grief they reached an orgasm in half. In the next meeting, he finished without any problems. After that, he said that he wanted me more (and 20 minutes passed), pestered, cuddled, caressed, moaned, said that he had finished, but there was no sperm.

He's got a stake from a blowjob. But I'm not going to come from a blowjob. He confesses his love and I feel that he wants me. He takes serious steps in a relationship, I also really like him, there is a sexual attraction, but the sex itself is awkward, complexes even begin to arise, which is not worth it for me. I understand that talking will solve everything, but while the tongue does not turn to discuss it with him, I'm afraid to offend. Otherwise, the guy is perfect for me.

I'll warn you right away, everything is fine with my appearance, misfires were very rare with previous partners. Maybe someone had a similar experience, what could be the reasons? The question is mostly for the guys.
