Two serious issues : Mind and showers

I have noticed that I have not solved two problems, which may lead to relapse in future.

So the first one is my mind. Although I have abstained for such a long time, my mind is still set on PMO. I just can't forget all of this and pretend that I don't know it. Plus I am on NoFap forums daily, and it reminds me of it.

The problem is that my mind is probably still in recovery after so many years of addiction and too often I find myself thinking about sex (I am 20.5 and single yet). As you may know, the thoughts lead to urges and more thoughts about sex. If I'm lucky, it doesn't last too long and I have a wet dream (without visuals) and it goes away for another period of time.

And there's a second problem. As I have the urges, the biggest threat to relapse is the shower. Not that I can't control myself or anything, but when I wash my penis, it just triggers me a little bit. So when I have urges, that little tiny bit of trigger can be like playing with fire near a place where gasoline is poured out.
So basically the problem I have is that I don't know how to stop thinking about sex so much and how to wash my penis without triggering myself.
