Ok so I pride myself on my dick sucking ability and have gotten great feedback. But there is this one guy that I just can't get to cum. I end up sucking his balls while he's jerks himself. I asked him about it and he said that he doesn't really cum from bjs. I really want him to so I feel like I've tried everything, deepthroating, playing with the tip, using my tongue a lot. Anyone have more suggestions??

I am putting this on myself because I get pleasure when I give him pleasure. Make sense?
