I can't see any rhyme or reason as to why they take it sometimes and take either part or none of it at others. Most people around here just put the bags on the curb - I put them in a can and that can went three collections without being touched. I emptied the bags onto the curb and they took it all. Sometimes, I'll put two full cans out and they take it all. For any ladies that have issues with our porn stemming from insecurity - don't worry about it.
Men are visual.
Porn is a shortcut. Sure, when we started masturbating at puberty we used to fantasize alot more than we do now, but that was only due to the lack of access to quality porn. Its tough for a 12 year old to get his hands on a four hour lesbian compilation tape. Plus, fantasy takes longer and is more work. Again, don't worry - we're not comparing them to you.
