Can't get it up in the shower

Very nice kissing and hugging and washing everything and caressing in the shower.  This should have me up and doing it quite easily.  I'm in heaven just looking at River.  Heaven. But no erection.  Compare this to last August when just being in the shower with River gets it up and I have to jack off in the shower.  Jacking off in the shower without lube isn't easy but I did it without a second thought.  Six months ago.  Six months of sub-mediocrity.  I have to call last night and this morning an F.

"I want to feel that tongue thing on my dick."  "That can be arranged."
