Per drilla and marinera — it is like anything else, you can over do it. If you aren’t an “addictive personality” then there probably isn’t a problem. Alcohol analogy: Some people do fine having a drink or two. Others have to get drunk every time they drink.
As an Off-Topic aside — I wonder how much of this “porn desensitization” stuff I hear about has to do with CRAPPY PORN????
There is a lot of unerotic unexciting junk out there, poorly acted, poorly lighted, poorly edited — why would it be a surprise that you couldn’t be aroused by it?
If I go to a regular movie that is poorly acted, poorly lighted, poorly edited, I don’t find it satisfying either. But I don’t get all “OH I AM DESENSITIZED TO MOVIES!!!!!!!!”. I just realize it is a bad movie.
