He means nothing to me
Why does he mean nothing to you?
I've told him before I would never want to be fucked by him.
Its okay to not want to be around someone, but you shouldn't put someone down when its uncalled for. It can be degrading to be told something like this and can cause long term self esteem issues.
I was bored and I thought it was funny to troll him with the \"Your dick is tiny\" post.
You sound like a bully to me. Would you want to be put down in such an arrogant manner too? Learn how to reject people gently and stop insulting others with petty remarks.
