Is it normal for guy friend to get hard as f*ck after saying something like this?

Summary:

My best guy friend got the hardest erection I’ve ever seen him have after I told a story of a former good guy friend showing me his penis platonically in elementary school.

More information:

I was hanging with my best guy friend and some other friends.

I shared about a time a former good guy friend showed me his penis non-sexually in elementary school.

Here’s a summary of the story I shared:

A former good guy friend kept saying “weenie”, and I kept asking him “what’s a weenie?” (I genuinely didn’t know that word for penis.) I kept asking him, but he didn’t answer me. And I asked him again, and then he showed me.

I didn’t actually say any more detail other than “he showed me”, but it was obvious what I meant.

After I told the story, my best guy friend got an erection that turned out to be the strongest hard-on I’ve ever seen him have. (And he still had it even when he left for the night to go home, almost 2 hours later.)
