How much hentai+Porn is too much?

I have been cleaning my hardrive of hentai and porn since last week. I currently have:

HENTAI: 1.93GB (8665 files)
PORN: 4.98GB (8032 files)
TOTAL: 6.91GB (16697 files)

So how much is too much? How much do you have?

thx you for the advices. I will delete a lot more... I didn't realize I had a lot. I didn't watch them for 15 years and just keep downloading...
