I'm sure he does love you...but lets face it we'd all pretty much rather scratch our own eyes out than have a discussion with our spouse that would make us vulnerable.
I used to get so nervous talking to my H that my voice would shake...he of course, would give me one word responses. That's why it's so important to have these discussions continually...so you both can stop being uncomfortable about it. My H is now getting to the point where he's initiating some R conversations with me, or volunteering more info when I ask a question. It just simply takes time, consistency & repitition.
Also, regarding your sexual activity w/him....tell him what you like. I've had to be very blunt w/my H about this...but now he does what he knows I like.
