Caught my friend touching himself, should I talk to him?

Anonymous
I accidentally walked in on a friend of mine touching himself, I should've knocked, i know but I didn't and there's nothing I can do about that now. I quickly left his house right then.
We have been avoiding each other for days now and I miss him so much, should I approach him and talk about what happened or should I keep on avoiding him. I miss him too bloody much and it is frustrating, he is my favourite friend.
