My bf  has a low sex drive  compared to me, and on the  occasion  that we do have sex he very rarely makes an effort to make me cum. I can't get there from vaginal sex and need clitoral stimulation, but he doesn't make an effort to get me off. And when we use my vibrator it makes him cum faster. He doesn't like going down on me and gets impatient, acts uninterested and does as little if anything to get me off. Sometimes he turns away to laugh when I make a face. He's a great guy in all other respects, but I can't seam to get through to him about the importance of this aspect of our relationship.
