Like if I am working super hard or in a strange place for work and have no access to sex, I watch porn. I wouldn't say a lot of it, but a little every day.

But then when I am in a normal groove where sex is pretty much a daily thing, I don't watch it all. I don't miss it. Similarly I do miss real sex and find myself more sensitive when I get back to it. Now having a lot of sex desensitizes me to sex a little, but usually a short break takes care of that.

I just don't find any diminished appetite for real human intimacy because of porn. They are two different things to me, even though one is sort of half-assed substitute for the other.
