Why do you ask 'besides' ( the exploitation, drugs, etc etc' ) ?
isn't that itself a bloody good and a good enough reason?
I personally find porn dehumanising. It reduces people - imo - to rutting animals. I don't like that.
I find that increasingly what was really extreme porn has now become mainstream, bordering on 'vanilla' and this, imo, can cause issues when people who have little or nothing to compare it to, think that this is what sex is. When anal, for example, is part of everything and you see things like going from one to the other and back again, you think do people know about the hygiene implications of this? (Leaving aside other issues, and pain and long lasting continence issues from using an out hole as an in hole, iyswim...)
I am concerned that there are people who do not do it through choice and that I cannot identify which people do it because it is their life long ambition and dream, and which people do it because they have either been trafficked, or they need money for drugs, or they have been so abused in life that they see no other life for themselves. I don't want to risk being part of something that continues to abuse and exploit someone.
Selfishly, I do not want to be compared to women who are far more attractive and sexual than I am. I would not want to feel like the person I was with wished I looked like them and not me. I also would not want them to feel that they could pull me around, twist me into position, put me at risk of an infection by transferring bacteria from bowel to vagina and invite their pals to join them. (ok that last one is just my personal dislike of this apparent trend for there to be several men using (and using is the word!) the body of a single woman.
I used to watch it (as I am sure is obvious!) but my views have changed as I have read more, and through reading been given a wider understanding, and I would never watch it again.
I realise that everyone has different opinions on it and we all have the right to our views, and since you have asked for our views, this has been mine.
