My partner and I had the opposite issue. After being long distance, only seeing each other on weekends, he moved close to me and when he’s not otr we see each other every day now. We had gotten in the rut of working long distance and didn’t know how to balance, especially since we are also engaged and involved romantically as well. We finally found ways to liven things up and make distinct times for play. It helped us both to feel more in control. Also, I attribute our fantastic communication skills to being long distance and beginning our relationship in kink. There’s no room for misinterpretation when playing. I like to push him and have gotten to where he has no need to safe word because I can tell when he’s close to going over the edge.
A little rambling but I guess over all I try to spice things up. Pick their clothes out, have them write/read their deepest fantasies, control their food, put them in chastity. Something you don’t usually do that can change it up. And schedule time to play, video chat is amazing. And in the end I truly believe the LDR will be a blessing.
