My boyfriend can’t stay hard

My boyfriend and I we’re gonna have sex for the first time the other day, but he couldn’t stay hard. At all. I would suck his dick and it would get hard, but as soon as he went to put it in me it got soft....

We are talking about it rn and he got horny again and started watching porn and has had no trouble being hard for like the last hour. I joked about it with him in the day I said “oh maybe I’m not attractive enough” and we laughed it off.... but now i feel like maybe that is the truth.

I don’t know. I’m super butthurt. We’re 17, so erectile dysfunction shouldn’t be a problem should it?

I don’t know.
