Dear passion, how do you know he's bi if he's never been with another man?
Your friend is doing you a favor by not taking your relationship to the next level. What he knows is that married men don't usually react well to their wives having an affair, which to an extent you already are with your online activities.
At this point I'd usually suggest you do one or two things; (1) spice things up with some sexy lingerie, videos and (or) toys, (2) see a counsellor to attempt to resolve your problems. In your case I'm going to suggest a third alternative; tell your husband you have something he's not using and would he object to loaning it out a few time a week, or whatrver schedule your other married with children duties will allow? Your last sentence (below) indicates to me that this is what you really want anyway so why not cut out the first two suggestions and proceed to the desired end result;
"I would like to turn it up a notch but I don't know if I should keep hinting it out due to I'm scared he'll just distance himself away. Can someone please give me some advice?"
Who knows, maybe there's a guy (or another woman) he has the hots for and you can have some sort of an arrangement.
