her probable problem is you are looking at gay/bi and she just wonders who or what she married.
my wife knows that I look at straight porn on my pc frm time to time, and have downloaded some scenes to dvd. we have watched them a little, she doesn't have the interest that she did yrs ago, overall her interest in sex is way down.
I can remember yrs ago when a neighbor got some porn on VHS tape and we watched it at home after the kids went to bed. John Holmes was on one part of the tape, and she was kinda freaked out, I remember her saying to me before, "i thought you were big, but there's one guy on here that's huge." well, it was Holmes. I thought maybe she wanted something that big, but she said, what do yo do with all of that, I would not fuck him. we watched the whole thing, and she said I was bigger than most of the guys in the movie, and joked we should make a porn movie. she noticed all the gals giving the guys BJ, and asked me I would like that. I said yes, of course, and later she gave me her first BJ, not my first. we had sex, and she found my cock got big and hard again faster if she blew me, so thereafter my cock rec'd lots of BJs. if we were out, the wife would tease me, by putting her tongue in her cheek briefly. my cock would go to instant chub with just the that little action.
