Is it weird I had to convince him to use my shower?

The first time I stayed at his in the morning I asked if I could use his shower.
He got me a towel and flannel and even had a spare toothbrush.
I borrowed one of his t-shirts since my top was dirty from all the night before.
When he stayed at mine for the first time I laid out a flannel, towel and du-rag plus a toothbrush.
He slept til late then only brushed his teeth.
This time he tried to do the same but I insisted that he could use my shower.
And he kind of reluctantly used it.
He was in there a while I'm guessing because my water pressure is so low.
But when he came out he was fresh and clean.
What I find more odd is that he new he was staying over but didn't even think to bring anything of his own.
Is this odd?
