I might be in the minority here, but I think you should mention to your H that this has been happening, and you have told him to stop. It has 2 benefits -- one, you are upfront and honest with H, and 2, it brings up the jealousy juices in H. Always a good thing for him to think others want you. And there is a third benfit. Men don't respect a "no" when it comes from a woman. If your husband tells him not to call you, it will stop.
