I don't mean to come off as a scumbag here. I'm sorry if it seems that way
Not to me you have not come across as a scumbag. I see zero wrong with adult porn using freely consenting actors or downloading such materials.
You do need to worry however about running into underage illegal porn while searching for or downloading legal porn however.
One college student look at what was in fact an FBI child porn honeypot web site without any illegal materials on it.
However just his visit was enough for the FBI to get a search warrant six months later and his home was raided and all his computers taken away.
They found no illegal material but for one thumbnail of a picture that was not on his computer and using that one thumbnail of a picture have him convicted of having child porn.
You do need to be damn careful when surfing the web for free porn as beside the risk of getting illegal materials on your computer you are increasing the likelihood of getting malware.
