Re: Question for men
Those two stars have enormously large breasts, and I expect that was why he picked them. That doesn't mean that he *prefers* large breasts - a lot of people look for porn for novelty.
I look at porn for the sex acts, almost never for the stars. I have occasionally searched for porn of types that I don't normally watch just out of curiosity - but that I think is the action of someone who watches frequently and is looking for novelty.
Its also possible that they were a couple of names he saw somewhere and that he wasn't specifically looking for big breasted women.
I am concerned about what my wife would think about my porn habit - but I've never thought about what she would think about the porn stars themselves, I've never though of comparing them to my wife at all. My porn use is all about vicariously enjoying sex acts that I can never do in real life.
Its hard to know, and I think in the end unimportant. He watched some porn - maybe for the novelty of different looking women, maybe for the specific sex acts. He is embarrassed about it and may still not feel comfortable telling you what he watched and why. Even if I told my wife I watched porn, there are some things I watch that I don't think I could admit to.
Since watching for sex acts seems the most common motivation, maybe see it that fits. If you have figured out what acts he has been watching, are they something you are willing to do for him? (you don't have to, but if you are OK with it it would be a good experiment to see how he reacts).
