Those cold feet will go well with your cross-country ski regimen.
I'm sure everyone's situation is different, so nobody will know better than you if you should confront him about his porn use. One thing seems to come out in every statistical report I've seen, though. Porn use diminshes a M's sex drive and in the extreme leads to ED.
If I was using porn and was called on it, I'd appreciate it to be done in a non-confrontational and non-judgmental way. In his mind, he probably has a reason for it. My guess is he either feels sexually inadequate or unable to have the sex he wants with you. (Those don't have to be true to be real to him, btw.)
To let him know that you're up for whatever, whenever and wherever he wants would be helpful. From what you've said about him, indicating that it wouldn't have to be a deep emotional event for him each time might help, too.
I wouldn't expect you to hold back from telling him that it hurts your feelings that (or at least makes you wonder why) he would rather MB than ML to you. That deserves an answer, IMO.
Good luck. Like I said, only you know if you should call him on it.
